Abstract :
In this paper, the authors propose a novel multi-step PWM inverter for a solar power generation system. The circuit configuration is constructed by adding a bi-directional switch to the conventional bridge type inverter circuit using the isolated DC power supply for which the solar cell is very suitable. The new type of PWM inverter presented has many features such as good output waveform, small size of filter, low switching losses, and low acoustic noise. In this paper the authors describe the circuit configuration, control method and the characteristics of the system, and they also investigate the relation between the inverter and the solar cell characteristics. Finally, some simulation results and experimental results are shown
