Abstract: A voltage measurement device for pulse-width modulation (PWM) signals is provided, which includes a conversion circuit and a processing circuit. The conversion circuit receives a first PWM signal and a second PWM signal from a motor driving device, and converts the first PWM signal and the second PWM signal into the absolute value signal and the polarity signal of the line-to-line voltage signal between the first PWM signal and the second PWM signal. The processing circuit converts the polarity signal and the absolute value signal into a first integral signal and a second integral signal, and reconstructs the line-to-line voltage signal according to the first integral signal and the second integral signal so as to obtain the reconstructed voltage signal of the line-to-line voltage signal.

Abstract: A motor drive is provided, which includes a control circuit, a first transistor, a first comparison circuit, a second transistor and a load. The control circuit includes a first output terminal and a second output terminal; the first output terminal outputs a first control signal; the second output terminal outputs a second control signal whose phase is inverse to the phase of the first control signal. The gate of the first transistor receives the first control signal. The first comparison circuit compares the gate-source voltage with a reference voltage to generate a first comparison signal. When the first comparison signal shows that the first control signal is reduced to be lower than the reference voltage, the second control signal generated by the second output terminal is transmitted to the gate of the second transistor.
