| Abstract: | A strructure for PWM boost DC_DC converter based on PCM （Peak Current Mode） 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 - comparator. 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. |
