【摘要】 三相桥式全控整流直流电源的工作过程,要求任何时刻都必须有两个整流器件同时导通,才能形成导电回路,其中一个为共阴极组的,另一个为共阳极组的。晶闸管是应用的主要整流器件,所以,要确保整流电源正常工作,晶闸管控制极(也称门极)的脉冲触发控制电路就非常重要了。就如何得到可靠的晶闸管触发控制脉冲做一简要的分析。更多还原

【Abstract】 In order to ensure the close circuit, it is requested that two rectifier components must work at the same time at any time for three-phase rectifier DC power. One was within common cathode and the other was within common anode. Silicon controlled rectifier(simplified as SCR) was the popular rectifier component. So, the pulse triggering control circuit was very important to make stable and reliable work process for SCR and DC power. How to get correct pulse for SCR was analyzed.更多还原
