PCT No. PCT/CN96/00092 Sec. 371 Date Aug. 11, 1999 Sec. 102(e) Date Aug. 11, 1999 PCT Filed Oct. 17, 1996 PCT Pub. No. WO98/00903 PCT Pub. Date Jan. 8, 1998A phase-shift thyristor trigger circuit, including a synchronous signal sampling circuit, a waveform shaping, integrating and comparator circuit, a high-frequency modulating pulse distributor circuit, a power amplification and high frequency pulse rectifier output circuit, characterized in that said synchronous signal sampling circuit includes a transformer, wherein its secondary inductance and a capacitor form a LC resonance circuit for selecting (via transformer coupling) synchronous signal from the main circuit. The trigger circuit connecting with a thyristor main circuit can make up a unified thyristor integrated module. The module is small in size, strong in antiinterference ability, has no requirements for phase sequence and number, and has a broad voltage adaptive range. |
