Secondly, the operating principle and the mathematical model and the control method about the three-level voltage source high power factor PWM converter are analysed .The generation of the PWM trigging pulse control signal are introduced emphatically. On the basis of this, the hardware experimentation circuits are built with DSP and CPLD, and the trigging pulse signal is generated exactly. The feasibility of the circuit is verified by the experiment result.
