Loss Equalization by Pulse-Voltage Injection Two-Phase PWM Scheme using 5-Degrees-of-Freedom Variable Switching Pause Period

Year: 2025

Type: article

Abstract: This study improves the previously proposed two-phase pulse width modulation (PWM) scheme with 2-degrees-offreedom (2-DoF) variable switching pause periods for equalizing device loss in an unbalanced three-phase inverter. ThisPWMscheme is extended to incorporate 5-degrees-of-freedom (5-DoF) variable switching pause periods, enabling individual loss adjustments for each device. Theoretical and numerical results demonstrate that the proposed 5-DoF PWM scheme effectively equalizes losses for each device in an unbalanced three-phase inverter.
