Abstract
This paper presents a solar-powered five level output voltage of a DC-to-AC converter using simplified Capacitor Voltage Controlled Scheme. It is configured by the combination of thin-film silicon Photovoltaic panels, insulated gate bipolar transistors, capacitors, power diodes and boost converter. A boost converter in-conjunction with PI controller ensures voltage balancing across the input DC series-connected capacitors. The system possesses the following characteristics: (i) it is portable (ii) it has very low total harmonic distortions (iii) It is cheap and simple to design. (iv) It utilizes single DC source. (v) It uses capacitors with appreciable capacitances (vi) the solar panels used are shadow tolerant due to the design of the thin-film silicon module. The following results were obtained: Stabilized five level output voltage inverter with THD of 0.95% and modulation index of 0.9. Power rating of 2.0 kW at a time interval of 0 ⩽ t ⩽1.8 seconds. The MatLab/Simulink software was used in this work.
