Power supply device for electromagnet
专利汇可以提供Power supply device for electromagnet专利检索，专利查询，专利分析的服务。并且PURPOSE:To increase the accuracy of the titled device at the rise of current and to improve the conversion efficiency by connecting a bridge circuit consisting of switches and a diode between an electric power converter and an electromagnet. CONSTITUTION:An auxiliary converter consisting of a high speed element such as a transistor (TR) 23 is connected in series to a main converter consisting of thyristors 2a, 2b, and the switches 5, 6 are connected between these converters and the electromagnet 4. In the 1st mode, the switches 5, 6 are turned off and the voltage of capacitors 3b, 3c in a filter 22 is kept at a fixed value. In the 2nd mode, the switches 5, 6 are turned on and said auxiliary converter with superior response is actuated simultaneously with turning on of the switches. In the 3rd mode for the decay of current, the switches are turned off and the diodes 7, 8 return the energy of the electromagnet 4 accumulated in the 2nd mode to the power supply.，下面是Power supply device for electromagnet专利的具体信息内容。
