In this work, the proposed control is based on digital bipolar PWM Switching which reduce the magnitude of the low order of harmonic components existing in the input AC supply in order to improve the output power quality of grid connected PV inverters and lower equipment costs for these systems.
A bipolar PWM single-phase inverter is a type of power electronic device used to convert DC (direct current) power into AC (alternating current) power with a single-phase output.
It operates a single-phase pure sine wave inverter. Then, the high order harmonics content is ameliorated by filtering the inverter output. The concepts of Bipolar and Unipolar SPWM represent two pivotal control strategies in power inverter.
This control is based on the single phase inverter controlled by bipolar PWM Switching and lineal current control. The electrical scheme of the system is presented. The approach is widely explained. Simulations results of output voltage and current validate the impact of this method to determinate the appropriate control of the system.
