4 / 10 page 4 follows. For AC200V line : VDRM and VRRM : 800V For AC400V line : VDRM and VRRM : 1,600V Between AC line and bridge rectifier, use appro- priate AC line filter. It reduces the noise entering into the equipment not so as to cause any unde- sired behaviors. Furthermore, it suppresses con- ducted emission from the equipment. As are ex- pected, external stresses on diode and thyristor, such as surge voltage and current, can be de- creased by such filter. ●Thyristor 1, What’s thyristor Thyristor is considered as a diode and a switch connected in serial. Same as bipolar transistor, thyristor is driven by current. With respect to bipolar transistor, when base current is applied, collector current of hFE times base current flows. In contrast, thyristor is switched on by gate current that is higher than a specific value (gate trigger current). The follow- ing figure illustrates these relationships. You will see that collector current of bipolar transistor flows during the whole period when base current flows, but thyristor keeps anode current flowing even after the gate current is cut off. So, you need not supply thyristor with continuous gate current TDK 3-phase line filter and internal diagram Thyristor (SCR) i v E Anode Cathode Gate iG vT i E iG Bipolar transistor (NPN) Collector Emitter iC vCE E Base iB vCE(sat) iC E iB hFE×iB Anode Cathode Gate Thyristor |
