Embodiment Construction
[0011] Below the present invention will be further described in conjunction with the embodiment in the accompanying drawing:
[0012] like image 3 Shown: includes electrolytic capacitor 1, electrolytic capacitor module PCB board 3, electrolytic capacitor module 4, support connection terminal 5, main power board 6, etc.
[0013] The present invention changes the traditional processing method of using film capacitors instead of electrolytic capacitors and complete machine replacement, and separates the bus electrolytic capacitors from the main power board to form an electrolytic capacitor module. The electrolytic capacitor module 4 is composed of electrolytic capacitor 1, electrolytic capacitor module Composed of PCB board 3, the electrolytic capacitor module PCB board 3 is placed on one side of the electrolytic capacitor 1, the electrolytic capacitor 1 itself has a positive terminal and a negative terminal, and the positive terminal and the negative terminal of the electrolyti...
