1. , for a control method for LED drive system, comprising:

  • Compare reacting the unlatching of reverse-blocking tetrode thyristor that is connected with LED drive system and the voltage of off-state and first threshold voltage;

    When this voltage is less than first threshold voltage, determine that this reverse-blocking tetrode thyristor disconnects, produce the leakage current maintaining reverse-blocking tetrode thyristor and normally work.
