Abstract
An uninterruptible power supply system including a rectification circuit, a power calibrating conversion circuit, an inverting conversion circuit, an LC circuit, a first output switch, a second output switch and a relay switch is disclosed. The rectification circuit couples to the main electricity. The power calibrating conversion circuit couples to the rectification circuit, and includes an independent drive unit and a switch unit. The inverting conversion circuit couples to the power calibrating conversion circuit. The LC circuit couples between output neutral terminal and output ground terminal. The first output switch couples between the LC circuit and the inverting conversion circuit. The second output switch couples between the inverting conversion circuit and output live terminal. The relay switch couples between the input neutral terminal and the LC circuit. When the relay switch turns on, the input neutral terminal connects with the output neutral terminal through the LC circuit.
