Abstract :
A small uninterruptible power supply (UPS) with a function-controlled PWM charger and SPWM inverter has been realized. The system has high reliability, low total harmonic distortion and fast dynamic response of the output voltage of the inverter, and strong load adaptability. The system performances are verified by experiments
