A Novel VFVDC Optimized Full Bridge Inverter Control Strategy for Independent Solar Power Systems

Project Code :TEPGPS539


The main objective of this project is to reduce the problem of power harmonics, and compared the proposed VFVDC optimized control strategy with the SPWM control method


In this project, the independent solar power system (ISPS), including the maximum power point tracking (MPPT) technology and the DC (direct current) to AC (alternating current) full-bridge inverter (FBI) control technology. This study combines perturb and observe (P&O) algorithm based on the output voltage control strategy and the proposed optimized FBI control strategy to the ISPS. The proposed variable frequency and variable duty cycle (VFVDC) optimized FBI control strategy had adjustable frequency and duty cycle. The proposed VFVDC control strategy was compared with the sinusoidal pulse width modulation (SPWM). When the output of FBI was at a low voltage level, the operating frequency was 10 kHz. Conversely, when the FBI gave a high voltage level output, the operating frequency was 1 kHz. This control improved the switching loss of 4 power MOSFETs in the FBI and thus improved the performance with a low harmonic amount. The simulation results of this method can be evaluated by using Matlab/Simulink Software.

Keywords: Variable frequency and variable duty cycle control strategy, maximum power point tracking, solar power systems, and full bridge inverter.
