ABSTRACT:
A power conversion apparatus includes: a reference signal generating circuit for generating a reference signal which has a first frequency; a first power converter for converting D.C. power into A.C. power which has the first frequency; a transformer connected to the first power converter; a carrier signal generating circuit for generating a carrier signal which has a second frequency which is higher than the first frequency; a second power converter having a plurality of switching devices and as well as converting the output from the transformer into A.C. power which has the second frequency; a command signal generating circuit for generating a command signal for commanding the quantity of the output from the second power converter; and a second-power-converter control circuit for generating a drive signal for driving a plurality of the switching devices of the second power converter in such a manner that the drive signal is generated in response to the reference signal generated by the reference signal generating circuit and a command signal generated by the command signal generating circuit and as well as in synchronization with the carrier signal generated by the carrier signal generating circuit.
