Abstract

The invention discloses a driving circuit structure of a motor controller, which has: a base plate, a pole plate, a phase plate and a bridge arm, the pole plate includes a positive pole plate and a negative pole plate, the phase plates include an A phase plate, a B phase plate and a C phase plate, The bridge arm includes an upper bridge arm and a lower bridge arm; a positive plate, a phase plate, a negative plate, a B phase plate, a positive plate, a C phase plate, and a negative plate arranged in sequence on the substrate; between the positive plate and the A phase plate , There is an upper bridge arm between the positive plate and the B-phase plate, between the positive plate and the C-phase plate; between the negative plate and the A-phase plate, between the negative plate and the B-phase plate, and between the negative plate and the C-phase plate There is a lower bridge arm; both ends of each bridge arm are connected to the pole plates on both sides of the bridge arm, and the packaged IGBT is replaced by a MOS tube, which reduces the cost under the premise of satisfying the function.

Description

technical field [0001] The invention belongs to the technical field of motor controllers for automobiles, and in particular relates to a driving circuit structure of a motor controller. Background technique [0002] At present, the state strongly supports the development of new energy vehicles, and pure electric vehicles have become a hot research topic in the entire automotive industry. As the brain of the entire drive, the motor controller is an important part of the entire power system, especially important. [0003] In the process of realizing the present invention, the inventors found at least the following problems in the prior art: In the traditional art, the packaged IGBT is used, and the cost is high. Contents of the invention [0004] The technical problem to be solved by the present invention is to provide a driving circuit structure of a motor controller that uses MOS tubes instead of packaged IGBTs and reduces costs on the premise of satisfying functions. ...
