摘要
在多数逆变电路的仿真中,通常都是直接采用Matlab提供的PWM发生器,建立逆变电路的仿真模型,很少根据PWM产生的机理,建立PWM发生器的数学模型。对单相桥式逆变电路进行仿真时,建立PWM发生器的仿真模型并和Matlab下提供的PWM发生器的仿真模型进行比较,仿真结果表明,根据PWM产生的原理建立的PWM发生器仿真模型的正确性,为PWM产生模型的建立提供了更广阔的选择空间。
In most of the simulation of the inverter circuits,the PWM Generator in Mtatlab is applied in general The simulation model is established,it is not usual to establish the mathematical model of PWM generator on the bas is of the mechanism of PWM generator.The mathematical model of PWM generator is established,and it also be compared with the PWM generator simulation model in Mtatlab.The simulation results show that the PWM Generator simulation model established based on the mechanism of PWM generator is correct,it provides a wide space for PWM generator simulation model.
