Abstract:
A convertor apparatus includes: a main circuit unit which converts an alternating current to a direct current and outputs the same to a DC link; a DC link capacitor; an alternating current voltage detection unit which detects an alternating current voltage crest value of the main circuit unit; a DC link capacitor voltage detection unit which detects a DC link capacitor voltage value; an initial charging unit which includes a switch for opening and closing an electrical path between the main circuit unit and the DC link capacitor and a charging resistor; a current detection unit which detects a current value flowing into the main circuit unit or flowing out of the main circuit unit; and a voltage reference value setting unit which sets the voltage reference value in accordance with the current value when the switch is adapted from to be opened into to be closed.

Claim (Index 4):
The convertor apparatus according to  claim 3 , wherein the voltage reference value setting unit stops a change process with respect to the reference voltage value when a difference between the allowable in-rush current value and a current value as detected by the current detection unit when the switch is adapted from to be opened into to be closed is smaller than the current reference value.
