Abstract: This paper presents a two-phase interleaved critical conduction mode (CRM) power factor correction boost converter with a variation-tolerant phase shifter (VTPS), which ensures accurate 180 phase shift between the two interleaved converters, which converters single phase 230V to three phase 410V. A feedback loop similar to a phase-locked loop controls the amount of the phase shifting of the VTPS. The proposed VTPS has better immunity of process, supply, and temperature variations than the conventional phase shifter. This boosted DC source applied to hybrid multilevel inverter, It consists of a standard 3-leg inverter (one leg for each phase) and H-bridge in series with each inverter leg. The three phase inverter output voltages, harmonic performance of induction machine current, induction machine outputs and THD is available by using simulation of MATLAB/SIMULINK software.
