摘要
通过分析研究单片机87C196MC波形发生器产生PWM脉冲及死区延时的工作机理,提出一种通过调整单片机死区时间实现DC/DC变换器PWM控制的新方法,给出了其编程设计思路、理论分析与实验结果。
Through analysis and research on the working mechanism of producing PWM outputs and dead-time by single-chip-computer 87C196MC's waveform generator, a novel PWM method by regulating the dead-time is presented to control the DC/DC converter. The programming principle, theoretical analysis and experiment result are expatiated.
