The effect of the pulse-width modulation scheme on the efficiency of a three-phase Y-inverter with a wide range of output voltages and currents is investigated experimentally in this paper. The efficiency measurements obtained while conducting experiments on a GaN-based Y-inverter prototype indicate that no pulse-width modulation scheme results in higher efficiency of the Y-inverter over the entire range of motor operation. In other words, depending on the operating conditions, a discontinuous PWM results in a higher or lower efficiency than a continuous sinusoidal PWM. As a result, there is a chance that using a hybrid modulation strategy will improve the efficiency of the Y-inverter. Furthermore, the distortion effect caused by inappropriate inductor and capacitor value selection is highlighted.
