==Original Abstract Submitted==

A motor drive system includes a MUX circuit, a DC voltage scaling circuit, a fault detection circuit, an ADC, and an FPGA. The MUX circuit selectively establishes a MUX input signal path and a MUX output signal path. The DC voltage scaling circuit measures a DC link voltage. The fault detection circuit receives the output DC link voltage and outputs one of a normal operation signal or a fault signal in response to comparing the DC link voltage to one or both of a U/V reference voltage and an O/V reference voltage. The ADC converts one or more input analog voltages into respective corresponding output digital voltages. The FPGA is in signal communication with the ADC output (ADC) and the MUX circuit, and is configured to control the motor drive system based on a comparison between one or more of the output digital voltages.
