Abstract
In a control circuit for controlling a power converter that includes a switch, a power supply circuit outputs electrical power, and a command generator generates a switching command that controls switching operations of the switch, based on the electrical power output from the power supply circuit. A failure mode determiner executes a determination of whether which of failure modes has occurred in the power supply circuit, and outputs a result of the determination. A switch controller selectively executes, based on the result of the determination, a first switch control task and a second switch control task. The first switch control task forcibly shuts down the switch independently of the switching command, and the second switch control task enables the switching operations of the switch to be continuously controlled based on the switching command.
