Claim:
1. A power conversion apparatus, comprising: a switch circuit which drives switching elements based on a control signal; a feedback section which performs feedback control; a signal output section which outputs the control signal based on a controlled variable of the feedback control; an output value detecting section which detects an output value outputted from the switch circuit; and an operation determining unit which has an operation stop determination section which determines whether to stop operation of the switching elements based on a rate of change of the output value, and an operation start determination section which determines whether to start operation of the switching elements based on the controlled variable, wherein the operation stop determination section determines whether to stop the operation of the switching elements based on the controlled variable if the rate of change of the output value is less than a threshold, and the operation stop determination section determines whether to stop the operation of the switching elements based on the output value if the rate of change of the output value is equal to or more than the threshold.
