Abstract :
The use of a new soft switching inverter topology, the resonant pole inverter (RPI), for harmonic compensator realization, is proposed. Using resonant transitions to minimize switching losses, the topology is suitable for use with GTOs and other gate turn-off devices. Switching frequencies on the order of 10-20 kHz at multikilowatt power levels are feasible. A current-mode modulation strategy is proposed and is seen to realize good spectral characteristics. Extensive simulation and experimental results of a 10 kVA GTO resonant pole inverter switching between 10 and 20 kHz confirm the validity of the approach
