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 15):
The AC-DC conversion device according to  claim 1 , wherein\n the major circuit portion further includes a current sensor sensing an alternating current of the alternating current power supply, and the control circuit senses a conduction width of the alternating current based on a sensed value of the current sensor, and performs a protection operation for protecting the plurality of switch portions in the case where the conduction width is a threshold or more.
