PROBLEM TO BE SOLVED: To obtain a power converter by which output power not containing switching noise can be obtained. SOLUTION: DC power generated by a DC power supply 1 is converted into AC power by an inverter circuit 2. Switching noise contained in the AC power is sufficiently small. An AC motor 3 is driven by the AC power and a generator 4 is driven by the AC motor 3 and a generator 4 is driven by the AC motor 3 to output AC power which does not contain switching noise. The AC power is amplified by an amplifier 5 and supplied to an AC motor 6. |
