A dual motor controller for dual motor hybrid electric vehicle was developed. The overall design scheme of the controller was described. The structure, hardware and software of the system were analyzed. A design scheme of dual motor controller based on double side water cooling IGBT was proposed. The thermal simulation of double side water cooling radiator was carried out to study its heat dissipation effect on IGBT module. The bench test of the prototype was carried out. The experimental waveform showed that the dual motor controller had a good control effect.
