A Multi-mode High Power Motor Controller

Abstract

The invention provides a multi-mode high-power motor controller which comprises two sets of control units. Each set of control unit comprises a control circuit and a power loop, wherein the control circuit sends control signals to the power loop according to the working modes of the motor controller, and the power loop conducts electricity generation control or driving control over a motor according to the control signals. The working modes of the motor controller comprise the double-circuit independent or parallel generator control mode, the double-circuit independent or parallel driving motor control mode and the single-circuit generator and single-circuit driving motor control mode. According to the multi-mode high-power motor controller provided by the invention, compared with the prior art, universal interchange between generator control and driving motor control can be achieved through the single controller, and the control power of the single controller can be improved through double-circuit same-mode parallel output.

Description

technical field [0001] The invention relates to the technical field of vehicle motor control, in particular to a multi-mode high-power motor controller. Background technique [0002] With the development of automobile technology, more and more vehicles adopt hybrid power or pure electric power output. The power core technology of a hybrid or pure electric vehicle is to use a high-power permanent magnet motor to provide electric energy (generator) or drive power (motor) for the vehicle. The power generation or electric function of the permanent magnet motor requires a permanent magnet motor controller to control it control is required. The existing permanent magnet generator controller and drive motor controller are independent control devices, which only have a single function of power generation or drive control, and a single motor controller can only control one motor. The universality of the motor controller is relatively low. Difference. At the same time, the external...

The existing permanent magnet generator controller and drive motor controller are independent control devices, which only have a single function of power generation or drive control, and a single motor controller can only control one motor. The universality of the motor controller is relatively low. Difference

At the same time, the external wiring of the traditional motor controller adopts the connection method of OT lugs pressed and fastened by bolts, which makes the external insulation and sealing protection and the convenience of installation and use poor; the external water cooling interface of the motor controller adopts the hose sleeve clamp lock The tight way makes its installation and use less convenient
