A close up of voltage regulators.

What is Voltage Regulation?

Although the principles of voltage regulation may be inherently complex, the concept at the heart of it is straightforward. You're talking about the ability of any electrical system to provide the constant (or near constant) voltage necessary to successfully and safely operate in a wide range of load conditions.


Voltage Regulators

A voltage regulator is a circuit that both generates and manages a secure, fixed output of voltage in whatever power system it is installed in. Essentially, it's making sure that the voltage coming from the power supply is always in whatever range necessary to be compatible with other components.


To that end, there are a few different types of voltage regulators to concern yourself with. One of these is called a linear voltage regulator, which is commonly used in many commercial devices in particular. It employs a "series pass transistor" to make sure that the output voltage stays consistent. It is simple, has low output noise, and offers excellent line regulation. It does have a limited voltage range, however, making it unacceptable for certain types of applications.

Another type is called a switching voltage regulator, which is inherently more complicated but highly efficient. These types of regulators can sometimes cause electromagnetic interference, however, so you must also be careful when using them.


Finally, there is a shunt voltage regulator, which controls the output voltage via a low-resistance path for excess current to bypass the load. It's simple and highly precise, but has limited load current handling.


Typically, the end application will dictate which type of voltage regulator should be used.



Factors Affecting Voltage Regulation

The number one factor that affects voltage regulation is the variation of the load in question. If that load is increased, it will sometimes cause a voltage drop. This refers to the amount of voltage loss that occurs as a result of resistance. That voltage regulator will then need to make up the difference to preserve the safe operation of not only the electrical system but whatever component it is connected to.


There are other factors that affect voltage regulation as well, with temperature being chief among them. If a voltage regulator is suddenly subject to extreme conditions like intense heat, it could change properties like line resistance. This would change how hard the voltage regulator had to work to maintain that consistent voltage, or if it was even able to do so at all.


Obviously, the tolerances of any component attached to the system would also impact voltage regulation. The tighter the tolerances, the more effective the voltage regulator will be at performing its primary function.


As is true with other types of mechanical components, wear-and-tear and maintenance (or a lack thereof) can also impact voltage regulation. As a voltage regulator ages after periods of heavy use, it will naturally become less effective. Its performance may suffer and its ability to accurately regulate voltage may be negatively impacted. At that point, it would either need to be repaired or fully replaced depending on the specifics of the situation.




Why is Voltage Regulation Important?

  • Ensures Equipment Safety. Proper voltage regulation always helps to minimize the possibility of dangerous conditions like an arc flash. This can cause not only severe burns to anyone in the immediate area, but long-term injuries and even fatalities due to a catastrophe like a fire as well.
  • Improves Productivity & Efficiency. Without proper voltage regulation, you're likely looking at a lot of equipment and systems that malfunction in unpredictable ways. This leads to unplanned downtime, which isn't just frustrating - it's also massively expensive. Voltage regulation keeps power systems running as consistently and as efficiently as possible, meaning that your workers are spending less time dealing with issues and more time being productive.

  • Prevents Damage to Electronics. Another core reason why voltage regulation is so important is because it helps to prevent damage to mission-critical equipment and other components. Proper voltage levels help prevent thermal stress, which reduces the risk of a failure. It also helps to maximize the lifespan of your equipment as well, all while cutting down on unnecessary maintenance costs.
  • Enhances System Reliability. Equipment that constantly cycles on and off due to inconsistent loads goes through an incredible amount of unnecessary stress over time. This requires downtime for maintenance that, even if it is planned, is still costly. It also reduces the lifespan of the equipment as well. Voltage regulation helps enhance system reliability in a way that prevents all this from happening.
  • Prevents Data Corruption. Voltage irregularities can lead to sudden system shutdowns, which can lead to corrupt and otherwise lost data. Proper voltage regulation helps make sure this isn't something that you or your own customers have to spend time worrying about.

Using Medium Voltage (MV) with Power Distribution for Industry provides an efficient delivery of High Capacity Power to Manufacturing Facility and Industrial Production Floors. A higher voltage provides a more “efficient” path for “AC Current” to travel to equipment. Large Motors and high inrush starter loads require much more Startup Current, medium voltage power distribution within a plant will provide an efficient capacity of Amperage for this high demand equipment. If production equipment in a Plant operates at lower voltage (LV), the delivery mechanism of higher voltage, closer to the equipment seeking the higher amperage, makes for more capacity available to the loads. This is achieved by the installation of step down function transformers, allowing the medium voltage (MV) to deliver higher capacity amperage “near” the loads. Then step down voltage at or near the equipment to the usable voltage. Benefits of Medium Voltage in a Facility -Higher Amperage Capacity delivered closer to Equipment Seeking Current (Amps). -Less “Current” loss during distribution through plant to various loads. -Lower “Pipe and Wire” costs as higher voltage requires smaller wire size to transmit. -More reliability in overall plant equipment: ie. Affects of power anomalies from lower voltage, sags, surges, failure of Machine Equipment Components. Disadvantages of Medium Voltage in a Facility -Higher cost to Utility for setup -Specialized Maintenance at higher voltage levels -Potential first costs higher for substation and distribution equipment up front, but lower cost of ownership over time. Low Voltage for Industrial Loads Low voltage distribution in a Plant can be installed successfully with a very constant load profile and demand. If there is larger equipment such as motors and processing that cycle on and off with large inrush current demand, this will affect the other areas of the Plant. These “surges” in demand for Current in these high demand inrush devices, can starve or pull down overall voltage in the other areas in the plant electrical distribution, or the entire plant. This will cause Power Supply failures in other equipment which seeks a constant voltage, or will burn components of other equipment due to variable voltage events. Over time this greatly affects a Plant’s Maintenance budget. Benefits of Low Voltage in a Facility -More Familiar Installation and Voltages for most Electrical Contractors. -Immediately available equipment, shorter lead times. -Simpler design and operation of electrical distribution and Electrical One Line. -Less step-down transformers within Facility and Electrical One Line Disadvantages of Low Voltage in a Facility -Exposed to more “Load” created anomalies that may affect other equipment -Limited amperage “Choke Points” for distribution and installation of larger equipment -Current loss from LV distribution through plant. -Susceptible to Inrush Current affect on immediate area or entire facility. -Higher “Pipe and Wire” costs as lower voltage requires higher amperage and larger wiring. Description and Uses of Low (LV) and Medium Voltages (MV) Low Voltage: 1kV - 15kV Typical City Use Power Grid Activities -Residential Use: (120v, 240v) -Commercial Building Use: (120/240v Single/Three Phase, 480v Three Phase) -Manufacturing and Industry: (480v Three Phase) -Localized Utility Distribution: Transformer to Load Medium Voltage: 13.8kV-34.5kV -High Density Data Center Uses -Large Manufacturing, Semiconductor -Motors, Compressors, Large Use Industrial Process -Electrical Utility Distribution, Long and Short Line distances High Voltage: 35kV and larger, 138kV -Long Transmission Lines Substation supply lines from Power Utility Sources -Industrial Processing Facilities, Steel, Mining. -Large transit requirements such as Railways and Commuter trains See your Voltage Correction Specialist to discuss Medium Voltage Power Distribution Options and Corrective Measures for your Facility Power Issues.

High Density AI compute performance chips like Nvidia Geoforce and now Blackwell B200 chips are requiring up to 300 watt, 400 watt, and 1200 watts. New rounds of chip development are considering up to 3000 watts of power per chip and requiring MEP Engineering design to consider bringing higher voltage closer to the Rack Loads. Why Medium Voltage UPS Systems Higher voltage carried over distances is more efficient than lower voltages carried over the same distance. Medium Voltage (13.8kV, 34.5kV) requires lower current (amps) to achieve the same capacities as low voltage (480v/208v), which exponentially changes the amount of power you can move from Point A to Point B, point B being the Rack loads. 480V Power Distribution for Data Centers In a legacy data center, medium voltage would be delivered to a substation or switchboard on-site. Transformers then step down medium voltage to 480V, which is widely used in data centers for the last 35 years. The typical legacy larger data center delivers 480 volts through the input switchgear, Uninterruptible Power System (UPS) via it’s Maintenance Bypass Switchboard route, and on to a Floor Power Distribution Unit (PDU). At the PDU, the load is stepped down via a internal PDU Transformer to usable 120/208V and 120/240V, which panels of breakers, or sub-feed breakers on the PDU support the actual breakers for servers. Low Voltage UPS Systems are limited to certain capacities to accumulate kW output for larger 2500kW or 5000kVA capacities. See Diagram 1.1
