LOAD CONTROLLER AND ELECTRIC VEHICLE HAVING THE LOAD CONTROLLER

摘要

A load controller and an electric vehicle having the load controller are disclosed. The load controller includes a casing; a busbar module, the busbar module including a DC busbar and an AC busbar connected to a load; a capacitor connected to an external DC power supply, the capacitor being connected to the DC busbar; an IGBT power module, an input end of each IGBT being connected to the DC busbar, and an output end of each IGBT being connected to the AC busbar; a heat-dissipating module, the heat-dissipating module including multiple heat-dissipating fins, each IGBT in a same column of IGBTs being sandwiched between adjacent two heat-dissipating fins; a driving circuit board, the driving circuit board being electrically connected to each IGBT; and a control circuit board, the control circuit board being connected to the driving circuit board, where all of the busbar module, the IGBT power module, the heat-dissipating module, the driving circuit board and the control circuit board are mounted on the casing. The load controller according to an embodiment of the present invention is high in cooling efficiency, good in cooling effect and small in size.
