UPS provides stable power supply for continuous operation of production equipment.This article de-signs a single-phase uninterruptible power supply with an output of 30V AC.The circuit consists of a single-phase bridge inverter circuit controlled and driven by a rectification circuit,a boost circuit,EG8010 and IRS2113S chips,and an auxiliary power supply.When the mains power is cut off,it automatically switches to a 24V DC reg-ulated power supply(simulated battery)to ensure the normal operation of the equipment.After testing,this design has low distortion of sinusoidal voltage waveform,and the voltage adjustment rate and load adjustment rate are not more than 0.5%.It also has functions of overcurrent protection and overvoltage protection.
