Abstract
How to turn the DC power supply (24 V) into AC power (220 V, 50 Hz) and load feedback power supply based on single-phase full-bridge inverter circuit has been discussed, and it is converted to a stable frequency power supply for a number of electrical appliances such as lights and computer requirement use. SG3525 chip fixed-frequency pulse width modulation circuit and field effect transistor (N channel MOSFET) whose switch speed quick, nothing secondary break down and good hot stability have been applied sufficiently. Inverter main part has been composed of DC/DC circuit, input protection circuit, output protection circuit, overheat protection circuit, DC/AC conversion circuit, and full-bridge circuit. The overcurrent and overheat circuit as well as the normal work light have also been designed. Practice has proven that the system is stable, has good utility, low-cost, and strong practicability. It can be used as a variety of portable electrical general power supply.
