According to the EMC definition, the electronic device needs to meet EMC design specifications, on one hand, it needs to ensure that the electronic device has a certain degree of immunity to electromagnetic interference existing in the environment, and on the other hand, it is required that the electromagnetic interference generated by the electronic device in the operating process to the environment cannot exceed a specified limit value.
An automotive motor controller is a typical electronic device on which electronic components such as a connection harness, a PCB, a power module, and a capacitor module are laid out. When the EMC scheme is designed, a general design idea is to add filter devices such as a magnetic ring and a magnetic buckle at a direct current end and a three-phase end, and add filter capacitors, a shielding case, a grounding design and other measures on a filter PCB on a transmission path.
