AI Technical Summary
Disconnecting the circuit is a challenge when integrating the automotive electric motor controller (ISC) and the battery current control module (BCCM), especially when it is difficult to achieve compactness and efficient integration of the power system without using high current contactors.
A new circuit topology is adopted, including AC/DC power converters, transformers, switch bridges and active ripple energy storage circuits, and an isolated DC/DC power converter is formed through these components, and the active ripple energy storage circuit is used to reduce the size of the electrolytic capacitor, achieving functional integration of electromagnetic interference filters and rectifiers.
Integrating BCCM with ISC without using high current contactors reduces package size, improves the compactness and efficiency of the power system, and reduces the number of connectors and wires.
