The invention discloses a power converter with a multi-slope compensation mechanism. The multi-slope compensation circuit of the power converter comprises a plurality of first capacitors, a comparator and a plurality of first resistors. A node between the first ends of the plurality of first capacitors and the second end of the upper bridge switch and the first end of the lower bridge switch is connected with an inductor. A plurality of first input ends of the comparator are respectively connected with second ends of the plurality of first capacitors and are respectively connected with first ends of the plurality of first resistors. Second ends of the plurality of first resistors are coupled to a second reference voltage. The second input end of the comparator is coupled to a first reference voltage. The output end of the comparator is connected with the input end of the driving circuit. 本发明公开一种具有多斜率补偿机制的电源转换器。电源转换器的多斜率补偿电路包含多个第一电容、比较器以及多个第一电阻。多个第一电容的第一端以及上桥开关的第二端与下桥开关的第一端之间的节点连接电感。比较器的多个第一输入端分别连接多个第一电容的第二端，并
