THD Analysis of Twin Two-Level 5-Phase Inverter System for Multi-Level Performance using Two Switching Schemes

Twin two-level inverter system arrangement could be a wonderful option for a few applications like electric vehicles or large-power wind energy generation systems, as it required two disparate dc voltage sources to give high voltage to the system. In this tract, the author presented a five-phase twin two-level inverter system for multi-level performance utilizing two different switching schemes. The proposed method eliminates the voltage balancing problem that plagues multi-tier neutral point clamped inverters (NPCI) and may be operated by two DC sources of equal value. The proposed system produces voltage levels similar to a multi-level inverter and utilizes twin two-level inverter to overcome the complexity and cost issue of multi-level inverter. The proposed strategy has been validated as a consequence of the simulation findings.
