PROBLEM TO BE SOLVED: To provide an inverter, power conditioner, and control method for inverter, capable of eliminating current disturbances around a zero cross and achieving high efficiency and suppression in noise generation.SOLUTION: The inverter 1 operates an upper arm and a lower arm of each leg to alternately turn on and off by a PWM system in a predetermined period including a zero cross where positive and negative polarities of an output AC current change with each other and operates only one arm of each leg to turn on and off by PWM system in any other period than the predetermined period. |
