摘　　要：提出一种新的混合脉冲密度调制的方法来调节感应加热电源的输出功率,详细分析了混合脉冲密度调制技术的原理和控制策略,并与已有的脉冲密度调制方法进行对比,证明这种方法控制脉冲分布均匀,输出电流平稳、连续,控制简单,还实现了控制方法的模块化设计,可通过增减基本控制模块来灵活改变输出功率的级数,提高了控制方法的灵活性。A new hybrid pulse density modulation method to regulate the output power of the induction heating power supply was proposed. The principle of the hybrid pulse modulation technique and the control strategy were analyzed detailed,and it was compared with the conventional pulse density modulation method. It was prove that this method has the advantages of symmetrical control pulse distribution,smooth and continuous output current,simple control. It also achieves modular design,we can adjust the series of the output power flexibly through change the basic control module. And the flexibility of the control method is improved.
