Abstract:
An AC-DC conversion device that includes a major circuit portion and a control circuit is provided. The major circuit portion includes a converter in which multiple switch portions in a bridge connection include separately-excited switching elements and snubber circuits connected in parallel with the switching elements; and the major circuit portion is connected to an alternating current power supply and a direct current circuit and applies, to the direct current circuit, an alternating current voltage applied from the alternating current power supply by an ON of the multiple switch portions. The control circuit controls the voltage applied to the direct current circuit by controlling the ON timing of the multiple switch portions by inputting a control pulse to each of the multiple switch portions.

Claim (Index 19):
A method for controlling an AC-DC conversion device, the AC-DC conversion device including a major circuit portion including a converter and being connected to an alternating current power supply and a direct current circuit, the converter including a plurality of switch portions having a bridge connection, the switch portion including a switching element and a snubber circuit, the switching element being separately-excited, the snubber circuit being connected in parallel with the switching element, the major circuit portion applying an alternating current voltage to the direct current circuit by the plurality of switch portions, the alternating current voltage being applied from the alternating current power supply, the method comprising:\n controlling a voltage applied from the converter to the direct current circuit by switching an ON timing of the plurality of switch portions by inputting a control pulse to each of the plurality of switch portions; and reducing a control angle of the control pulse input to each of the plurality of switch portions in a range between 90\u00b0 and 180\u00b0 when charging a capacitance component included in the direct current circuit to a command value.
