Abstract
A proof-of-concept main inverter unit has demonstrated the operation of a pulse-width-modulated parallel resonant power stage topology as a 20 kHz AC space power source driver, showing simple output regulation, parallel operation, power sharing and short-circuit operation. The use of a two-stage DC input filter controls the electromagnetic compatibility (EMC) characteristics of the DC power bus, and the use of an AC harmonic trap controls the EMC characteristics of the 20 kHz AC power bus
