Printed circuit board and electric energy converter

Abstract

The embodiment of the invention provides a printed circuit board and an electric energy converter. The printed circuit board comprises at least one layer of copper foil; a fuse is arranged in the printed circuit board and is formed by copper foil; the fuse is connected with the current supply end, and the cross sectional area of the fuse is smaller than that of the copper foils at other positions within the preset range of the current supply end; wherein the current supply end is at least one or more of a power supply input end, a capacitor end and an inductor end; the printed circuit board also includes a plurality of devices that form a plurality of current loops, the fuse being located in a common area where the plurality of current loops have the common area. Therefore, when the current supply end fails or is abnormal, the fuse can be fused to protect the circuit; secondly, the fuse can be designed according to actual needs, and the printed circuit board is simple in process, small in size and low in cost; in addition, the number of fuses can be reduced, and the board area of the printed circuit board is saved.
