In order to improve the anti-jamming ability of IGBT drive circuit, the optical fiber isolation driver technology was used to isolate the control signal and drive signal of drive circuit by photoelectric conver-sion. The selection of transceiver,send and optical fiber in the medium voltage high-power SRD drive circuit were introduced. The concrete application, capability test and modality experiments were taken. The experi-ments prove that IGBT's optical fiber isolation driver technology can prevent interference of drive circuit, and improve dependability of the medium voltage high-power SRD in working.
