Abstract The control of Brushless DC Motor is a challenging task while interfacing with renewable power generation. Especially in photovoltaic power generation having issues such as low power extraction, lagging of current with respect to voltage generation, low load of drives, multi stage of power conversion and control complexity. In this paper Switched Inductor Quasi Z Source Inverter (SL-QZSI) introduces for photovoltaic fed brushless DC Motor drive for reducing multistage power generation, additional power extraction of photovoltaic and reducing complexity of control circuit. Switched inductor circuit is replaces single inductor of quasi z source circuit and extracting high power, improving efficiency without using voltage lifting unit, coupled inductors and transformers. The speed sensing and reference current is used to estimate an actual reference current and Maximum Power Point Tracking (MPPT) is used to tune various modulation value of reference current to generate Maximum Boost Pulse Width Modulation (MB-PWM) scheme. MPPT is generated modulation index value with respect to photovoltaic power conditions. The proposed topology is implemented using MATLAB/Simulink software to verifying about unique merits of power conversion stage and control performances of proposed switched inductor quasi z source inverter topology.
