UPS power inverter based on combination can be divided into the transformation type and model, set up the static switch type single phase transformation of UPS power main circuit diagram as shown. The figure shows that when the mains is normal, for the inverter output as the main power supply load. In order to facilitate maintenance, set up a manual maintenance bypass switch, namely access to bypass switch S, closed, and then make the S2, S3 and static switch. Under standby power supply power to the load, the UPS system away from the bypass system, which can do maintenance of inverter, static switch. When the inverter as primary power supply, first close the static switch and the bypass switch S2, S3, and then disconnect S1.
