Abstract

A power converter suitable for power elements of different sizes includes a base, a heat sink, a circuit board, and a power element. The base has a separating plate and an opening. The separating plate has a first stepped surface and a second stepped surface, wherein the first stepped surface and the second stepped surface are located at different levels. The heat sink is assembled on the base andis abutted against one of the first stepped surface and the second stepped surface of the separating plate. The circuit board is assembled on the base. The power element is disposed on the circuit board and is in contact with the heat sink through the opening.

Description

technical field [0001] The invention relates to a power converter, and in particular to a power converter suitable for power elements of different sizes. Background technique [0002] Various power converters have been widely used in various electronic products, such as power supplies, computers, UPS uninterruptible power systems, AC-to-DC converters, etc. Power converters provide stable constant voltage or constant current, and their main function is to convert The type of power supply at the input is converted to the type of power required by the load at the output. A general power converter includes power components (such as power transistors, power diodes, etc.) and heat dissipation devices (such as radiators and fans, etc.). Since there are various power components with different sizes or output powers on the market, at the same time, in order to match the power components with different sizes or output powers, there are corresponding radiators and fans with different ...
