Abstract :
This article describes the working principle and driving schedule of Three-phase bridge inverter, proposing a PWM Control Realization method which Duty Cycle is adjustable and the delay time of the switch tube on and off can be preset. The generator uses CPLD for hardware foundation, and based on VHDL hardware description language for the simulation test in Max+Plus. The PWM controller which uses CPLD greatly simplifies the control system´s hardware and software design, suitable for three-phase circuit with different topology structure, with in-system programmable, easy transplantation, strong controllability other significant advantages.
