在全桥无源逆变电路课堂教学中，移相调压控制技术是教学难点，学生对移相调压控制技术在全桥无源逆变电路中的应用学习非常困难。鉴于此，本文提出图例式教学法，具体做法就是首先将全桥无源逆变移相调压控制的工作原理通过生动和清晰的图形表示出来，将其工作原理分为六个工作阶段，每个工作阶段通过一个等效电路来阐述其工作过程。当学生明白其工作原理后，在MATLAB/Simulink中建立其仿真模型，最后将得出的仿真结果与理论波形进行比较，验证其理论分析的正确性。教学效果表明，相对于传统的“满堂灌”的教学模式，图例式教学方法能明显提升课堂听课效率。

In the classroom teaching of full-bridge passive inverter circuit, the control technology of phase-shifting regulating voltage is the teaching difficulty, and it is very difficult that the students study the control technology of phase-shifting regulating voltage for full-bridge passive inverter circuit. Aiming at the problem, the author proposed the legend type teaching method. The specific approach is that the paper gave the working principle of full-bridge passive inverter of phase-shifting regulating voltage through the vivid and clear graph firstly, then its working principle is divided into six stages, and each work phase was explained its working process through an equivalent circuit. After the students understand the working principle, the paper built the simulation model based on MATLAB/Simulink. Finally, the simulation results were compared with the theoretical analysis waveform to verify the correctness of theoretical analysis. The teaching effect showed that the classroom lectures efficiency improves significantly by the legend type teaching method compared with the traditional "spoon feeding" teaching mode.
