Abstract

This paper represents two-stage Permanent Magnet Synchronous Machine (PMSM) drive, consisting of a multistage DC-DC boost converter followed by a Z-source Inverter (ZSI), suitable for MPPT enabled Solar-Photovoltaic (SPV) based application. Available low voltage DC can be boosted up by the multistage DC-DC converter through which high gain can be achieved. A traditional ZSI is further used in the design to produce the three-phase AC power. The open loop speed control of the PMSM drive can be implemented by duty cycle control of the DC-DC converter. Furthermore, an incremental conductance (IC) based MPPT is implemented for extraction of maximum available solar power. The total system is simulated in the MATLAB Simulink and verification of the voltage and current characteristics of the different converters are carried out. Performance analysis of the PMSM drive is also carried out.
