A UPS includes an input that receives first power from a utility source to power a load and receives second power from the utility source. The load is separate from the UPS. An inverter receives when in a first mode, the first and second power and when in a second mode, the second power and not the first power. The second power is used to power the inverter. A bypass circuit is connected to the input and bypasses the inverter to supply the first power to an output of the UPS when operating in the second mode. A control module detects a voltage at the output of the UPS, integrates the voltage to generate a first sum, and subsequent to completing a transition between the first and second modes, adjusts an output voltage of the inverter based on the first sum to balance the voltage of the UPS. |
