Embodiment Construction
[0033] Below in conjunction with accompanying drawing and embodiment the present invention will be further described:
[0034] Such as figure 1 As shown, the housing A2 is an aluminum frame structure, and a cable waterproof joint C4 is fixedly arranged on the wall of the housing A2 for the convenience of outgoing wires. The top of the housing A2 is sealed by a housing cover A1, which is a rectangular aluminum piece, and the housing A1 is fixed to the housing A2 by a plurality of screws distributed along the edge. The bottom of the housing A2 is supported and sealed by the bottom plate A3, which is a rectangular aluminum piece, and the bottom plate A3 is fixed with the housing A2 by a plurality of screws distributed along the edge. The bottom plate A3 is a sandwich structure, and a water cooling cavity is formed inside the bottom plate A3. A plurality of cooling fins are distributed on the bottom surface of the bottom plate A3, and the cooling fins are integrated with the bot...

The invention discloses a large-power controller of an electric car. The front end of the top surface of a soleplate is provided with an AC (alternating-current) high-voltage large-current power supply / heat radiating aluminum block, the middle part of the top surface of the soleplate is provided with a power supply negative electrode conflux aluminum block, a phase-A high-voltage large-current output / heat radiating aluminum block and a phase-C high-voltage large-current output / heat radiating aluminum block are arranged between the power supply negative electrode conflux aluminum block and the AC high-voltage large-current power supply / heat radiating aluminum block side by side, the rear left part of the power supply negative electrode conflux aluminum block is sequentially provided with a phase-B high-voltage large-current output / heat radiating aluminum block and a phase-B high-voltage large-current power supply / heat radiating aluminum block from front to rear, and the rear right part of the power supply negative electrode conflux aluminum block is provided with a capacitance battery; a power plate is arranged right above the soleplate, and a control driving plate which is parallel to the power plate is arranged right above the power plate. By adopting the large-power controller of the electric car, the problem that a heat radiation and high-voltage large-current input-output passage cannot be compatible with the optimal EMC (electro magnetic compatibility) effect can be fundamentally solved, and the reliability of the product is good.
Description
technical field [0001] The invention belongs to the technical field of motor controllers, and in particular relates to a high-power controller for driving motors of electric vehicles. Background technique [0002] The electric vehicle drive motor controller is a device that uses a high-speed processor DSP with low logic voltage and current to control the inverter working in the environment of high voltage, high current, high temperature and strong electromagnetic field. Its layout structure needs to solve three main problems, namely: heat dissipation, high-voltage and high-current input and output channels, and the best EMC effect. However, the above three problems are contradictory to each other. Existing products seek a balance point inside the controller to build the structure, and the existing deficiencies lie in: [0003] 1) The structure is complex, bulky, difficult to assemble, high production cost, and difficult to mass-produce; [0004] 2) The problem cannot be so...
