A high power density dual-drive controller is developed to meet the requirements of electromechanical coupling system of novel hybrid electric vehicles. The structure design scheme of the controller is described in detail, and the hardware electrical principle and software control strategy are briefly introduced. The cascaded seven-channel cooling design scheme is proposed, and the heat dissipation effect of dual-drive controller is studied by finite element simulation. Finally, the bench test of the dual-drive motor controller is carried out with a prototype controller. The test results show that the dual-drive motor controller has a high-efficiency cooling effect and stable control performances.
