Abstract

The invention provides a water-cooled motor controller for a high power density electric vehicle. In the controller, an opening is formed at the bottom of one side of a shell, and a water cooling radiator is arranged at the opening; a power module, a direct current bus support capacitor, a pre-electrified resistor, a main relay and a current sensor are arranged in the shell respectively; the power module is arranged on the upper surface of the water cooling radiator; the direct current bus support capacitor, the pre-electrified resistor, the main relay and the current sensor are fixed in the shell respectively through bolts; the power module, the direct current bus support capacitor and the main relay are connected through a conflux busbar to form a high-voltage loop; a power factor correction capacitor is fixed on the conflux busbar; a drive circuit board which is used for a power module is arranged above the power module; a separator and a control circuit board are arranged above the drive circuit board sequentially; and a plurality of power cable connectors used for assembling power cables pass through the lateral wall of the shell. The water-cooled motor controller has the advantages of flexible and convenient operation process, strong radiation capability, high power density, good electromagnetic compatibility and safe and reliable use effect.

Description

technical field

[0001] The invention relates to a water-cooled motor controller. In particular, it relates to a water-cooled motor controller for a high-power-density electric vehicle with modular design, flexible configuration, and convenient wiring. Background technique

[0002] Due to the increasingly serious environmental protection and energy issues, the rapid development of the electric vehicle industry has been promoted. The core is to replace the internal combustion engine power system with an electric drive system or a hybrid drive system, and to partially or completely replace fuel with batteries as vehicle energy. As a key component of electric vehicles, motor controllers integrate microelectronics technology, power electronics technology, thermodynamics, modern control theory, and electromagnetic compatibility technology, and are increasingly valued by domestic and foreign automobile manufacturers and scientific research institutions.

[0003] There are many typ...
