This paper mainly uses EG8010 and LT8705 as the central module to rectify and stabilize the AC power supply and realize the conversion of DC to AC. Use this to design AC sine wave online uninterruptible power supply (UPS). LT8705 as the central module with high performance voltage stabilization effect and multi-compatibility function, is the preferred device. EG8010 is the core device of the inverter power board, which realizes DC-AC transformation through SPWM modulation and switches the power supply with Schottky diode to realize the uninterrupted power supply of DC power even if AC power outage. The experiment proves that the expected effect can be achieved.
