Abstract

A power converter device health check system includes a circuit that connects a power input to a power output, and that includes a first transistor directly coupled to ground and a capacitor in parallel with the first transistor. A controller device is coupled to the circuit and, during boot operations, prevents first power from being provided to the first transistor via the power input, and turns off the first transistor. While preventing the first power from being provided to the first transistor and with the first transistor turned off, the controller device provides second power to a circuit location in the circuit between the first transistor and the capacitor, and then determines whether a charge of the capacitor is below a threshold charge level. If the capacitor is below the threshold charge level, the controller device transmits a power converter warning message.
