Abstract

The invention provides a motor controller control panel which is suitable for a new energy vehicle, the motor controller control panel comprises at least four layers of PCBs, the surface layer and the bottom layer of the motor controller control panel are used for arranging signal lines of a motor controller, and the bottom layer of the motor controller control panel is used for arranging signal lines of the motor controller. The inner layer of the motor controller control board is used for arranging a power line and a ground line of the motor controller.

Description

technical field [0001] The invention relates to the field of motor controllers, in particular to a motor controller control board and a grounding method thereof. Background technique [0002] Nowadays, the EMC (electromagnetic compatibility) performance of new energy vehicles is becoming more and more important, and there are mandatory standards at home and abroad that require the EMC performance of complete vehicles. In new energy vehicles, the electric drive system is an extremely critical part, and its EMC performance can also determine the EMC performance of most complete vehicles. [0003] When conducting EMC tests on the electric drive system of new energy vehicles, the grounding problem of the control board is often the main source of EMC problems in the electric drive system. Under the 12V or 24V voltage supplied by the vehicle battery, the motor controller control board of the new energy vehicle needs to provide different power supplies to other electronic componen...
