Abstract
In this article, reduced switch-based fault resilience capable multi-level inverter (MLI) with phase disposition pulse width modulation (PD-PWM) strategy is implemented. For reliable power conditioning and monitoring of PV based systems multi-level inverter (MLI) received a lot of attention. The switching device quantity mainly influences of volume and reliability in a MLIs. It is a crucial challenge in on and off-grid applications. Because of the high failure rate of power devices, the reliability of MLI utilized in PV and grid-connected systems is very poor or susceptible. To reduce the switching losses and enhance the MLIs reliability with fault resiliency, the reduced switch component topology is proposed in this work. Instead of a single switch, the suggested configuration is employed with multiple switch fault resiliency, then the reliability of the inverter is enhanced. Further, the PD-PWM switching strategy is employed for the MLI operation. The proposed scheme offers an excellent performance with significant result of THD, switching losses, and efficacy. The implemented inverter topology with PD-PWM strategy is simulated in MATLAB/Simulink along with fault tolerance operation under normal and faulty operation. Also, the real-time operation of proposed topology with experimental setup is validated using field programmable gate array (FPGA) controller.
