ZXD800 15A switch rectifier is divided into four parts: 1. AC input rectifier and start the auxiliary power. Power conversion and output rectifier filter section 3. Phase shift control circuit portion 4. The microprocessor part (MPU) single-phase AC input prior input switch, and then after EMI filter circuit, the rectifier circuit, input rectifier circuit has to limit inrush current circuit of the rectifier input has smaller boot inrush current . Under normal circumstances of the rectified DC voltage of about 310V, supplied stage power conversion circuit. Phase shift control circuit is part of the oscillation phase shift of power generated and the closed-loop feedback regulation. Dc voltage and current feedback signals are compared with set values, respectively, constitute a particular frequency response of the closed loop regulation, is converted to a group having a phase shift of the pulse width modulated PWM signal supplied to the main circuit, so that the power supply reaches a predetermined voltage regulator and current limiting outer characteristics and requirements of the dynamic characteristics. The primary current, the output current of the main circuit overcurrent protection, overvoltage and short circuit protection on the output voltage. Microcontroller circuit power supply parameters for real-time acquisition and control of the normal operation of the power supply; accept keyboard commands; LCD display the power of real-time data and control menu; monitoring module via RS-232 or RS-485 to transmit power data, alarm information, and receive this keypad or upper system monitoring module set command. Auxiliary power rectifier internal control various power required by the circuit. Start the auxiliary power supply is used to provide power to start the required auxiliary power supply input voltage, and the work of the start of their no-load. Temperature detection circuit detects the temperature of the main radiator to give to the SCM system, SCM system fan control circuit according to the main radiator temperature control fan working condition. The parameters of the test battery, battery management (this feature only the RS-232 communication interface ZXD800 15A switch rectifier).
