Abstract: An electronic fuse apparatus is connected between a power side and a system side. The electronic fuse apparatus mainly includes an electronic fuse, a short-circuit protection switch, a current-sensing module, and a digital control module. The current-sensing module detects an operating current which flows from the power side to the system side. The digital control module generates a control signal to control the electronic fuse. When the current-sensing module detects that the operating current is over-current, the digital control module generates the high-level control signal to turn off the electronic fuse, thus providing an over-current protection. When a short-circuit fault occurs at the system side, the short-circuit protection switch is turned on to turn off the electronic fuse, thus providing a short-circuit protection.

Abstract: An inverter includes an inverter case, a plurality of power modules and a plurality of cooling fins. The inverter case includes an annular portion, a supporting portion and a cooling liquid flow channel. The cooling liquid flow channel is a sealed channel located in the annular portion and the supporting portion, and a cooling liquid inlet and an inverter case cooling liquid flow channel outlet are formed on the annular portion at two ends of the cooling liquid flow channel. The power module is arranged on the supporting portion, and the cooling fins are arranged on the cooling liquid flow channel, the fin parts of the cooling fins are respectively extended and arranged inside the cooling liquid flow channel, and the contact parts of the cooling fins are respectively extended to contact heat transfer parts of corresponding power modules.
