PURPOSE:To provide an inverter circuit, in which an output ripple is reduced effectively. CONSTITUTION:An inverter circuit includes a pair of PWM inverters that generate each output with opposite polarity, and the outputs from a plurality of inverter blocks 1 to 4, in which the inverters have different carrier wave phases, are connected in series or parallel. A synthetic signal of the outputs from the inverter blocks 1 to 4 is generated, and thereby a ripple factor is sharply reduced. |
