专利汇可以提供Electric power converting device专利检索,专利查询,专利分析的服务。并且PURPOSE: To get rid of the current control impossible area and make the control response and the power-factor of power supply side satisfactory, by mounting the forward converter such as thyristor-Leonard, etc. and the reverse converter such as thrystor-inverter, etc.
CONSTITUTION: This device is formed by the forward converter A consisting of thyristors 20W25, the reverse converter B consisting of main thyristors 1W6, diodes 7W12, and commutation condensers 13W18, and the control circuit C consisting of the voltage detection circuit 34, etc. And the voltage detection circuit 70 is connected to the output terminal of A, and based on the aforesaid output the polarity discrimination circuit 71 discriminates the polarity of A, outputs the discriminating signal "k" depending on positive or negative, and the inverter 72 outputs the inversion signal by inverting the signal "k". Also, the primary delay circuit alleviates the output signal of the voltage control circuit 43, namely, a frastic change of the voltage deviation signal.
