Abstract:
In this paper, the power loss occurs in single
phase nine level modular multilevel converter for different
pulse width modulation (PWM) techniques is investigated.
The comparative analysis is carried out under variable
switching frequency. The PWM techniques include phase
disposition PWM (PDPWM), phase opposition disposition
PWM (PODPWM), alternate phase opposition disposition
PWM (APODPWM), and phase shift PWM (PSPWM). The
simulation is carried out using MatLab-Simulink and
verified experimentally.
