Abstract: Outputs from first and second DC power supplies are controlled based on a first reactor current and a second reactor current. For controlling an output from a corresponding DC power supply, a relative maximum point and a relative minimum point as two inflection points are provided in a high current of the first and second reactor currents in one control cycle, by controlling on and off of switching elements. In a low current of the first and second reactor currents, inflection points more than in the high current are provided. Each of the inflection points on a side of the high current is provided at timing identical to the inflection point on a side of the low current.

Abstract: A battery string is configured such that a plurality of battery circuit modules can be connected in series. A middle point between a first capacitor and a second capacitor provided on a detection line connecting a positive electrode output line and a negative electrode output line of the battery string to each other is grounded by a ground line through a limiting resistor. During operation of the battery string, an electric leakage detection unit sets a battery circuit module in a pass-through state, and detects electric leakage in the battery string based on a differential voltage that is a difference between a first voltage being the voltage of the first capacitor and a second voltage being the voltage of the second capacitor.
