Title: Power conversion apparatus
IPC: H02M7/497
Filed: 2021-08-04
Abstract: PROBLEM TO BE SOLVED: To provide a power conversion apparatus the operation of which can be stabilized when a switching frequency is increased at a proper timing. 
     SOLUTION: A power conversion apparatus includes a self-excited power converter that performs power conversion between an AC circuit and a DC circuit, and a control device that controls a switching operation of a switching element included in the self-excited power converter. The control device calculates the deviation between a control command value to the self-excited power converter and a feedback value from the self-excited power converter. When the deviation becomes equal to or greater than a first threshold, the control device performs first control of increasing a switching frequency of the switching element. The control command value is an effective power command value for effective power which is outputted from the self-excited power converter. The feedback value is an effective power value which is calculated on the basis of an AC current and an AC voltage in the AC circuit.
