A New Five-Phase Coupled Inductor Inverter With Svpwm Method for Common-Mode Voltage Reduction

Abstract

In this paper, two carrier-based pulse-width-modulation techniques are proposed to reduce the common-mode (CM) voltage generated by the five-phase inverter using space vector pulse width modulation. This work presents multi-carrier interleaved PWM strategies to control common mode voltage (CMV) in three phase coupled inductor inverter (CII). In this paper Space vector modulation (SVM) algorithm is used for the control of pulse width modulation (PWM).[1] It is used for the creation of alternating current (AC) waveforms. Carrier-based pulse-width-modulation techniques are popular due to their simplicity, and have been widely researched for various three-phase inverter configurations. The five-phase inverters have more flexibility in reducing the CM voltage than their three-phase counterparts because they have more phase legs hence finer control over the star-point voltage of the load.
