Detailed Product Description：	In the bridge rectifier circuit, the diodes are replaced by the SCR is not controlled rectifier circuit became of it? In the bridge rectifier circuit, just put two diodes into the SCR can constitute a full-wave controlled rectifier circuitry. Now draw the circuit and waveforms (Figure 5), the thyristor controlled Nengkanmingbai very desired trigger pulse is how to generate it? SCR trigger circuit form many SCR T405-800T, common There RC-bridge phase-shift trigger circuit, single-junction transistor trigger circuit, transistor trigger circuit, using a small SCR trigger large SCR trigger circuit, etc. What is the single-junction transistor? What special features does it have? RBB called base resistance SCR 2P4M, and can be regarded as two resistors RB2, RB1 series [Figure 7 (b)]. Notably the resistance will change with RB1 emitter current IE is changed, having a variable resistance characteristic. If two base B2, B1 plus a DC voltage between UBB, the voltage at point A UA is in: if the emitter voltage UE
