This specification covers naval shipboard Power Electronic Conversion Equipment (PECE) design and selection of components. PECE consists of any power converter (see 6.4.3), inverter (see 6.4.11), or rectifier (see 6.4.19) that is stand-alone or part of a power distribution system. PECE utilizes solid-state power switching devices to provide user loads with required power level and quality to ensure safe and reliable operation. Examples of applications include, but are not limited to, variable frequency drives (VFD), frequency converters (see 6.4.6), power conversion modules (PCM), power conditioners, and other specialty power supplies. In a unidirectional design, PECE provides power conversion, power conditioning, and electrical supply to the loads. In a bi-directional design, PECE provides energy conversion back to the energy source or storage device. This specification applies to PECE for surface and submarine naval vessels (see 6.2), regardless of voltage level and output type.
