Single Phase Inverter

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.

Uninterruptible Power

A marine DC uninterruptible power supply is designed. The UPS adopts PIC16C73 single-chip microcomputer to realize the battery management. Both AC power and battery power, the output voltage stability in 23 to 24 v.Via advanced battery management, two sections of charging, equalized charging and floating charging can automatic convert and the DCUPS has many functions of protection, such as over-voltage protection ,under voltage protection and short circuit protection.The actual use on the ship and other occasions showed that the DCUPS is convenient and practical,and is more simple, reliable and longer emergency power supply than the traditional AC-DC uninterruptible power supply management scheme.
