ABSTRACT:
A power conversion apparatus comprises an inverter circuit for converting DC power into AC power which has a first frequency; a transformer connected to the inverter circuit. A cyclo converter circuit having a bidirectional switch controls a direction in which an electric current passes and converts the output from the transformer into AC power which has a second frequency. A switching signal generating circuit generates a switching signal for controlling the polarity of the bidirectional switch of the cyclo converter circuit in such a manner that the output voltage from the inverter circuit does not encounter a short circuit.
