Study on a Wind-Solar Complementary Power Inverter
This paper studies a wind-solar complementary singlephase sine wave power inverter, including the hardware structure, operating principle, and method to the charging and discharging design. A dual-level three-state intelligent float charging based on PIC single chip control is brought forward for combining the special characteristics of wind-solar energy system. It helps the automatic transfer between charging and discharging and active protection of the battery. Unattended wind-solar complementary power system is achieved. With the help of reasonable calculation and simulation analysis, the final parameters are determined. A prototype of 500W/220V/50Hz single-phase sine wave power inverter has been fabricated. Through the model experiment the output voltage waveforms are found in conformity at both no-load and full-load, and the THD is very low. Therefore, the workability and validity are proved.
