Example Embodiment
[0011] The present invention will be further described below in conjunction with the embodiments in the drawings:
[0012] Such as image 3 Shown: Including electrolytic capacitor 1, electrolytic capacitor module PCB board 3, electrolytic capacitor module 4, supporting connection terminal 5 and main power board 6, etc.
[0013] The present invention changes the traditional method of using film capacitors instead of electrolytic capacitors and replacement of the whole machine, and separates the bus electrolytic capacitor from the main power board to form an electrolytic capacitor module. The electrolytic capacitor module 4 is composed of an electrolytic capacitor 1, an electrolytic capacitor module The PCB board 3 is composed of the electrolytic capacitor module PCB board 3 where the electrolytic capacitor 1 is placed on one side. The electrolytic capacitor 1 itself has a positive terminal and a negative terminal. Insert the positive terminal and the negative terminal of the electro...
