Embodiment Construction

[0016] Below in conjunction with accompanying drawing and embodiment the present invention is described in further detail:

[0017] figure 1 The shown electric vehicle motor control device includes a controller 4; the output end of the IGBT drive power supply module 1 is connected to the input end of the IGBT drive circuit module 2, and the output end of the IGBT drive circuit module 2 is connected to the input end of the IGBT module 3, The output terminal of the IGBT module 3 is connected with the motor M; a current sensor 7 is arranged between the IGBT module 3 and the motor M; the IGBT drive power supply module 1, the IGBT drive circuit module 2, the IGBT module 3 and the current sensor 7 are all connected with the control Device 4 is connected. The current sensor 7 can transmit the current of the motor M to the controller 4 in a timely manner, so that the controller 4 can monitor the working state of the motor M. Once the motor M is abnormal, the controller 4 can turn off...

Abstract

The invention discloses an electric automobile motor control device, and belongs to the technical field of power electronics. The electric automobile motor control device comprises a controller. The output end of an IGBT drive power supply module is connected with the input end of an IGBT drive circuit module, the output end of the IGBT drive circuit module is connected with the input end of an IGBT module, and the output end of the IGBT module is connected with a motor; a current sensor is arranged between the IGBT module and the motor; the IGBT drive power supply module, the IGBT drive circuit module, the IGBT module and the current sensor are all connected with the controller. By means of the electric automobile motor control device, the problem that due to the fact that it is complex for an existing IGBT module motor to control a peripheral circuit and connection wires are more, the potential failures are more is solved.

Description

technical field [0001] The invention relates to the technical field of power electronics; in particular, an electric vehicle motor control device for an electric vehicle. Background technique [0002] With the depletion of global oil resources and the increasingly serious global greenhouse effect, countries around the world are vigorously developing a low-carbon economy. With the development of this trend, it has become inevitable for electric vehicles to replace fuel vehicles. [0003] IGBT (Insulated Gate Bipolar Transistor), an insulated gate bipolar transistor, is a composite fully-controlled voltage-driven power semiconductor device composed of BJT (bipolar transistor) and MOS (insulated gate field effect transistor), and has a MOSFET The advantages of high input impedance and low conduction voltage drop of GTR. The saturation pressure of GTR is low, and the current carrying density is high, but the driving current carrying density is small. It is very suitable for th...
