讨论了一种采用双斜坡补偿技术的峰值电流模式控制PWM升压型DC＿DC变换器结构，利用双斜坡信号差模输入方法有效消除了单斜坡补偿技术中存在的电路干扰对斜坡信号斜率造成的误差。利用一个求和比较器电路同时实现了电压和电流的双环反馈以及双斜坡补偿，提高了变换器的瞬态响应速度。

AstrructureforPWMboostDC_DCconverterbasedonPCM(PeakCurrentMode)is discussed in this paper,in which the dual slope compensation is utilized.The dual slope compensation can effectively eliminate the circuit interference error by the common-mode rejection of a sum-compa-rator.The converter can realize the function of slope compensation and dual feedback of current inner loop and voltage outer loop at the same time.The instant response of converters has improved.
