| 摘 要： | 如果采用阻容降压电源,目前技术只能采用半波整流电路来控制双向可控硅触发。按双向可控硅触发原理,使用全波整流电路采用特殊设计,让触发极G和主端子T1形成电压差,能导通双向可控硅;让触发极G悬空或处于高阻,能关断双向可控硅。这样,相同的阻容降压电源,提供的有效电流将增大一倍。

| Abstract: | If you uses a RC power supply, the current technology can only uses half wave rectifier circuit to control the TRIAC triggered. By trigger principle for TRIAC, using the full wave rectifier circuit with special design, letting the trigger electrode G and the main terminal T1 form voltage difference will trigger the TRIAC; and letting the trigger electrode G suspended or in high resistance will turn off TRIAC. So the same RC power supply will supply double current. |
