Internal layout structure of switched reluctance machine controller of electric vehicle

Abstract

The invention provides an internal layout structure of a switched reluctance machine controller of an electric vehicle. The internal layout structure comprises a high-voltage part, a low-voltage part and a radiator base (13). The high-voltage part comprises an IGBT module (1), a thin-film capacitor (2), a high-voltage copper bar and a pre-charge contactor (3). The high-voltage copper bar comprises a copper bar positive electrode (4), a copper bar U positive electrode (5), a copper bar U negative electrode (6), a copper bar V positive electrode (7), a copper bar V negative electrode (8), a copper bar W positive electrode (9), a copper bar W negative electrode (10) and a copper bar negative electrode (11). The low-voltage part comprises a low-voltage main control board (12) and a low-voltage connector (17). The low-voltage connector (17) is connected with the low-voltage main control board (12), the high-voltage part is arranged on the radiator base (13), and the low-voltage part is arranged above the high-voltage part. The hierarchical design of the high-voltage part and the low-voltage part is adopted in the longitudinal direction, and the internal layout structure is simple, compact in layout structure, high in system reliability and suitable for large-scale batch production.

Description

technical field [0001] The invention relates to an arrangement structure, and more specifically relates to an internal arrangement structure of a switched reluctance motor controller for an electric vehicle. Background technique [0002] With the rapid development of new energy vehicles, electric vehicles are getting more and more attention. The motor controller is the main core component of the electric vehicle. Due to the limitation of the use environment, the motor controller for the electric vehicle is required to have high reliability and high energy volume ratio, and the volume of the motor controller is required to be as small as possible for the motor with the same power output. Small; at the same time, due to the mass production of electric vehicles, the assembly of internal components of the motor controller is required to be suitable for mass production, so the interior of the motor controller is required to use a modular design, compact layout, and easy installat...
