Abstract：
 A phase-splitting zero cross trigger controller for switching capacitor of thyristor is sequentially composed of Hall detecting circuit serially connected to thyristor, signal converter to convert low current to square-wave voltage with same phase as that of thyristor's terminal voltage, zero cross detector, "OR" circuit whose input is the detected zero cross signal and the switching signal from main controller, time delay circuit, and high-frequency modulating, pulse isolating and amplifying circuit whose output is connected to control pin of thyristor. Its advantages are high correctness, speed and reliability.
