Abstract
The analysis of a PV solar energy electronics processing system, operating at the maximum power point (MPP) for commercial refrigerator supply applications is presented in this paper. The refrigerator is fed from a bank of batteries using two electronics processing stages. The first one is a step-up push-pull converter that is responsible for the dynamic of the refrigerator and the DC bus voltage control, and the second stage is a full-bridge voltage source inverter with three levels PWM modulation. A closed-loop voltage is used to control the step-up stage, and a closed-loop current to control the compressor starting current. The main features of this system are: simple control strategy, robustness, low harmonic distortion of the load voltage, and natural isolation. The principle of operation, design procedure and experimental results are presented. Keywords: DC-DC push-pull converter, PV solar energy, voltage source inverter.
