Abstract:
An uninterruptible power supply having efficiency power conversion has an AC to DC power conversion circuit, a battery power conversion circuit and a control circuit. The AC to DC power conversion circuit is parallelly connected to the battery power conversion circuit to convert the AC power of an AC mains into a DC power and supply the DC power to a load. When the AC mains stably supplies power, the control circuit controls to activate the AC to DC power conversion circuit and supply power to the load through the AC to DC power conversion circuit only. As there is only one power conversion between the AC mains and the load, the power conversion efficiency can be enhanced.
