Abstract
In various applications, including power supplies for superconductor insertion systems, grid-tied photovoltaic (PV) system and motor drives, three phase voltage source inverters are now commonly used where power conversion efficiency relies heavily on modulation techniques. Different types of pulse width modulation (PWM) techniques are used to mitigate this issue. Total harmonic distortion (THD) and switching energy loss are considered as the main performance parameter of inverters. But, the traditional techniques of PWM cause significant losses and exhibit low power conversion efficiency. A new modulation technique is proposed in this paper that offers lower THD and losses in power conversion. The proposed modulation technique is verified in MATLAB/Simulink environment.
