Design of inverter power supply for household solar power generation in pastoral area

The inverter power supply for pastoral area household solar power generation is developed in this paper. Based on SPWM technology, after passive filtering, the power supply with inverter can produce low-distortion high-efficiency sinusoidal AC power supply. When the power of loads is less than 300W and the DC input power supply is within 10V to 14V, the inverter can give the output of sinusoidal voltage 220VACα10%. It has the functions of under-voltage input protection and over-current output protection, and can automatically recover the normal operation state after elimination of under-voltage and over-current.
