摘要
针对制动能量回收中BUCK变换器的不稳定问题,从斜坡补偿的基本原理出发,设计了一种斜坡补偿电路,该电路采样简单的阻容电路和RS触发器对主控芯片TMS320F2812的PWM信号进行了修正,实验结果验证了理论分析的正确性。
Buck DC-DC converter has the problems such as instability in the application of regeneration brake system. According to the principle of slope compensation, simple slope compensation circuit is carried out for peak current mode converter. The slope compensation circuit is composed of one resistor and one capacitor in series to rectify PWM duty from control chip TMS320F2812. The experimental results show its validity and feasibility.
