Power Electronics

Power electronics are semi-conductor components used as power rectifier regulators and static electrical power conversion equipment, especially in uninterruptible power systems (UPSs). They also charge industrial batteries.

Power electronics products are used in:

  • Commercial and industrial battery-powered applications (e.g., industrial truck, on- and off-road electric vehicles, and automatic guided vehicles)
  • Communication-type battery chargers for floating and charging a battery and delivering power to telecommunication loads
  • Power conversion equipment in energy producing systems of 1,000 volts and below (e.g., microturbines, photovoltaics, and utility-connected power sources)
  • Power conversion equipment in UPSs (i.e., AD/DC, DC/AC, AC/AC, and DC/DC power converters), and flywheel energy storage systems
  • UPSs that provide quality and continuity of an AC power source with a UPS made up of semiconductor AC to AC power converter systems and rotary power converters (motor-generator sets) with a dedicated DC electrical energy storage capability (battery)
  • Utility-type battery chargers that power a DC load directly

Members influence international commerce by developing Standards that reflect the North American manufacturing market, facilitating trade through a focus on harmonization within the Americas, and reducing or eliminating tariffs on information technology equipment.


  • Maintains NEMA Standards for UPS, static (solid-state) transfer switches, and utility-type and communications-type battery chargers
  • Maintains NEMA PE 1 Uninterruptible Power Systems (UPS)—Specification and Performance Verification, which is based on the International Electrotechnical Commission (IEC) 62040-3 UPS performance standard
  • Serves as the Technical Harmonization Committee for the U.S.–Canadian bi-national project to maintain a Standard published by the American National Standards Institute (ANSI) , Underwriters Laboratories (UL)–Canada, and CSA on UPS safety requirements
  • Supports the operation of the U.S. Technical Advisory Group to IEC SC 22H that influences the harmonization of the IEC 62040-1 standard on UPS safety with the related U.S.–Canada bi-national standard
  • Engages with the U.S. Technical Advisory Group to IEC SC 22H, which is influencing the development of the IEC 62310 Standards for safety, electromagnetic compatibility, and performance requirements
