ABSTRACT:
A DC-to-AC electric power converting apparatus includes: an inverter circuit for converting DC electric power into AC electric power; a transformer connected to the inverter circuit; a cyclo-converter circuit for converting the frequency of the output from the transformer; a carrier signal generator for generating a carrier signal of a predetermined frequency; an inverter switching circuit for generating a signal for controlling the inverter circuit in synchronization with the carrier signal; a reference voltage signal generating circuit for generating a reference signal for the AC voltage to be transmitted from the cyclo-converter circuit; a first switching signal generating circuit for generating a switching signal in accordance with the reference voltage signal supplied from the reference voltage signal generating circuit and the carrier signal supplied from the carrier signal generator; and a cyclo-converter switching circuit for generating a signal for controlling the cyclo-converter circuit in accordance with the switching signal supplied from the first switching signal generating circuit.
