Patent ID: 7535737

Claim:
An AC/AC power converter configured to be mounted on a substrate, the AC/AC power converter comprising: a plurality of input ends; a plurality of output ends; first and second direct-current power lines; a multiple-phase converter including a first diode having its anode connected to one of said input ends and its cathode connected to said first direct-current power line, a second diode having its anode connected to said second direct-current power line and its cathode connected to said one of said input ends connected to the anode of said first diode, and a switching part selectively connecting another one of said input ends to either said first direct-current power line or said second direct-current power line, at least one phase of the multiple phase converter consisting only of said first diode and said second diode; at least one smoothing capacitor connected between said first direct-current power line and said second direct-current power line; and a multiple-phase inverter connected between said first and second direct-current power lines and said plurality of output ends.
