Real-time Performance Evaluation of Single Phase 7 Level Z-Source Boost Inverter

Multilevel inverter has been familiarized as a popular topology for DC-AC power conversion. This paper illustrates the real-time performance evolution of seven level zsource diode clamp multilevel inverter. The field programmable gate array (FPGA) integrated real time simulators consists of multiprocessor and computer clusters are the main hardware platforms for real-time simulations. The real time (RI) lab software enables the parallel simulation of an electrical circuit on clusters of personal computer running at sampling time 10 μs. The integration of multilevel inverter and z-source energy conversion are used for DC-AC converter for high power applications with low total harmonics distortion. An impedance network has two passive elements such as two inductors and two capacitors connected between DC power source and multilevel inverter circuit. It provides a unique feature such as the boost the inverter output voltage and reduces the harmonic content in the output voltage as compared to the classic multilevel inverter. The real time results are verified the proposed system with a specified time step 10 μs and frequency is 10 KHz.
