| 摘 要： | 针对传统单片机控制LCC谐振逆变器控制过程中出现的问题进行了理论分析:并基于ATgOPWM2B微处理器,提出了改进型半桥LCC逆变器的控制策略.改善后的LCC逆变器不但提高了频率分辨率,改善了启动和功率调节特性,而且解决了频率修改时的波形异常问题.基于理论计算给出了电路各参数的计算方法,然后通过详细的仿真分析优化了设计方案,最后通过试验验证了上述理论和仿真分析的正确性.

| Abstract: | The analysis and study of the problem accompanied with the control process of the LCC resonant inverter are presented.The proposed strategy is based on AT90PWM2B MCU.It enhances frequency resolution,and improves igniter quality and power closed loop character.Futher more,it can avoid the well-known waveform abnormity.The parameters are given by theoretical calculation,and then are verified by experimental results. |
