Control circuit for power converter

A control circuit for controlling a power converter that includes a switch, the control circuit comprising:

• a power supply circuit configured to output electrical power;
• a command generator configured to generate a switching command that controls switching operations of the switch, based on the electrical power output from the power supply circuit;
• a failure mode deter miner configured to:
• perform a determination of whether which of failure modes has occurred in the power supply circuit;
• and
• output a result of the determination;
• and
• a switch controller configured to selectively execute, based on the result of the determination, a first switch control task and a second switch control task,
• the first switch control task forcibly shutting down the switch independently of the switching command,
• the second switch control task enabling the switching operations of the switch to be continuously controlled based on the switching command.
