Abstract
A first current detector detects an output current of a modular uninterruptible power supply apparatus. Each of a plurality of power conversion modules includes a resistive element and a second switch. The second switch connects the first current detector and the resistive element in parallel in an ON state. Each of first control circuits turns on the second switch when setting a corresponding power conversion module to an operating state, and turns off the second switch when setting the power conversion module to a stopped state. Each of the first control circuits detects a shared current of the corresponding power conversion module based on a current flowing through the resistive element when the second switch is in the ON state. Each of the first control circuits controls a power converter such that an output current of the power conversion module matches the shared current.
