Zusammenfassung:	The system is an AC sine wave online uninterruptible power supply designed with STM32F407 as the main controller and full-bridge single-phase inverter as the core technology. The system is based on the STM32F407 single-chip microcomputer, and consists of a rectifier circuit, a BOOST circuit, a PFC power factor correction circuit, and a full-bridge single-phase inverter circuit. When the input of the system is switched between 29V~43V AC power supply and 24V DC power supply, the output voltage can maintain an AC sine wave with constant frequency and amplitude. Experimental data shows that the system has high operating efficiency and excellent stability.
