Abstract
A power system including a gate driver configured with test circuitry to detect faults is disclosed. The power system may be configured to test the fault detection circuitry in order to confirm its ability to detect faults. Various methods and circuit implementations are disclosed to determine the ability of the system to detect faults. The testing may include different configurations and protocols in order to make conclusions about which components are likely responsible for a failure. These components may include components included in the gate driver or externally coupled to the gate driver. The disclose approach does not significantly add complexity because a test input to initiate a test may be communicated from a low voltage side to a high voltage side over a shared communication channel.
