| 摘 要： | 在对现有感应加热电源功率调节方式比较分析的基础上,提出了一种脉宽移相调功与定角锁相控制相结合的方法来调节逆变器输出功率。该方法不仅满足了电压型逆变器的工作条件,而且实现了功率的大范围调节,主电路简单,可实现软开关。文中对输出功率与移相角的关系进行了理论分析,利用Matlab/Simulink软件搭建了仿真模型,并对该控制策略进行仿真及样机试验,结果验证了该方法的可行性。

| Abstract: | Based on the comparison analysis on available induction heating power modulation,it presents a method which combines pulse-width phase-shift power modulation with fixed-angle phase-locked control to adjust the inverter output power.It not only meets the work conditions of voltage inverter,but also realizes a large scale of power modulation.The main circuit is simple and the soft switching can be realized.It analyzes the relationship between output power and phase-shift angle.The control strategy is also sim... |
