Background technique

The rectifier input adjusts the shape of the current, or can adjust the shape of air flow, water flow or current. In power electronics: converting alternating current into direct current is called AC/DC conversion. The power flow of this conversion is from the power supply to the load. Copper busbars generally refer to copper busbars. Copper busbars are used to manufacture motor windings, high and low voltage electrical appliances, and switch contacts. headers, as well as indispensable conductive materials such as wires for power distribution installation. In the power conversion system, the high-voltage rectifier input copper busbar is used as a current transmission channel between the power supply and the electronic device. It can withstand higher voltage and current and transfer the input power to the target device through the low-resistance copper foil. ,At the same time, since the transmission of high-voltage electric energy may generate a large amount of heat, the rectifier input copper busbar usually needs to have a good heat dissipation design to maintain a stable operating temperature.
