[0002] At present, in order to meet high performance and low cost, more and more new energy vehicle manufacturers have begun to change from completely outsourcing the drive system to self-making part of the drive system architecture. As a third-party electric drive system supplier, in order to meet the different layout and interface requirements of vehicle manufacturers' self-made electric drives, it has become a trend to invest in the development of modular products for drive systems. For drive motor controllers, modular power components are the current main direction; through platform design, the power components can make the controller performance more excellent, be more adaptable to changing working environments, and meet users' requirements for energy-saving, efficient, stable and reliable drive systems.

[0003] Existing problems still exist: Most of the power components in the current market are power components for single controllers, with small power, unable to meet the strong power and extreme off-road requirements of the whole vehicle.
