Multi-input power converter and uninterruptible power supply having the same
First Claim
1. A multi-input power converter, comprising:
- input connection means having a first input terminal, a second input terminal and a reference ground terminal for electrically connecting to an input power system and receiving input currents from the input power system;
inductor means having a first inductor and a second inductor electrically connected to the first and second input terminals of the input connection means for charging and discharging the input currents;
switch means having a first AC switch unit and a second AC switch unit electrically connected to the inductor means for conducting the input currents;
rectifier means having a first rectifier and a second rectifier electrically connected to the inductor means and the switch means for receiving discharged input currents from the inductor means and producing rectified inductor currents when the input current is discharged from the inductor means;
output storing means having a first storing device and a second storing device electrically connected to the rectifier means for receiving the rectified inductor currents and charging voltages when the inductor means is discharged; and
switch control means having a control unit electrically connected to the first and the second AC switch units of the switch means to control the inductor means charging the input currents and discharging input currents to the output storing means by controlling the first and the second AC switch units turning on and turning off.

Abstract
A multi-input power converter and an uninterruptible power supply (UPS) having the same, wherein the multi-input power converter has input connection means, inductor means, switch means, rectifier means, output storing means and switch control means. The inductor means is electrically connected to the input connection means. The switch means is electrically connected to the inductor means for conducting input currents. The switch control means is electrically connected to the switch means to control the inductor means charging the input currents and discharging the input currents to the output storing means to perform the DC to DC converting, AC to DC converting and power factor correction functions by controlling the switch means turning on and off.
