Patent ID: 8896251

Claim:
A power electronic device electrically coupled to an electric machine installed at an operational site, the power electronic device comprising a digital signal processing (DSP) unit configured to: power a logic section in the DSP unit of the power electronic device; verify that an initial set of communication logic signals in the logic section is zero; verify that an initial set of gate signals is at a first predetermined level, the initial set of gate signals being measured at an output of a gate driver board; activate, in response to the verification that the initial set of communication logic signals is zero and the initial set of gate signals is at the first predetermined level, a plurality of electronic switches in a predetermined sequence to update the initial set of communication logic signals to a second set of communication logic signals in the DSP unit of the power electronic device; detect a voltage waveform at the output of the gate driver board; and determine a status of the power electronic device by comparing the voltage waveform against a reference voltage waveform.
