Abstract
A device configured to monitor a voltage at a voltage rail for driving a motor includes processing circuitry configured to receive an indication of a switching signal for a phase of a plurality of phases of the motor. Inverter circuitry associated with the device is configured to electrically couple the phase to the voltage rail or to a reference rail associated with the voltage rail based on a driving signal that is generated based on the switching signal. The processing circuitry is further configured to determine a measurement time to measure the voltage at the voltage rail based on the switching signal and generate, using an analog-to-digital converter (ADC), a set of measured voltage values based on the voltage at the voltage rail during the measurement time.
