Jyothi Journal on Power Systems Engineering 2322–0376 3 3 32 40 Power Conditioning System, Solar PV System, Three Level Diode Clamped Inverter, Closed Loop DC-DC Boost Converter, Current Controlled MPP, Level Shift SPWM Maximum Energy can be extracted from the popularly used PV systems by using Power conditioner circuit. Power conditioner controlled with FPGA is implemented in this paper. Variable DC power from the solar array [33][34] is converted to constant DC voltage using a Boost converter. FPGA controller adjusts the pulse width to maintain the output voltage of the boost converter constant. The obtained constant DC voltage is converted to 3-phase AC using a 3-Phase 3-level diode clamped inverter. Reference current at AC side of the inverter is controlled by current control MPPT based on six-region operation. 2-stage power conditioner for the Solar PV system is developed in MATLAB Simulink and Xilinx System generator tool. Simulated results are analysed using Bode plot and THD analysis. August - October 2015 Copyright © 2015 i-manager publications.
