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 5):
The AC-DC conversion device according to  claim 4 , wherein\n the voltage estimation circuit estimates the voltage from the formula\n V A-K =k ( V acpeak \u00d7sin \u03b1\u2212(\u00bc)Vdc), \n where V A-K  is a voltage applied when triggering the plurality of switch portions, V acpeak  is a peak value of the alternating current voltage of the alternating current power supply, Vdc is a direct current voltage of the capacitance of the direct current circuit, \u03b1 is the control angle, and k is a prescribed constant.
