Photoelectric conversion device for converting IGBT driving signal transmission based on CPLD

The utility model discloses a photoelectric conversion device for converting IGBT driving signal transmission based on a CPLD. The photoelectric conversion device comprises a digital controller, a power supply circuit, a voltage conversion circuit, a pulse signal identification and correction circuit and a pulse signal conversion circuit. Signals are identified and corrected in the transmission process through the CPLD, optical fiber signal transmission between a digital controller and a driving circuit is achieved, and the problem that in the transmission process of driving pulse signals, due to the fact that a transmission line is long, interference sources will interfere the pulse signals through parasitic capacitance and parasitic inductance of the transmission line, and the transmission time is shortened is effectively solved. The problem that the device is damaged due to misconduction and short circuit of an upper tube and a lower tube of the IGBT caused by distortion is solved, and long-distance transm
