Abstract

The boost voltage strategy of the hybrid system is based on the boost mode management, the boost target voltage decision, and the boost PI control. The specific contents are as below: boost mode control. The boost mode includes the initial mode, normal mode, shutdown mode, and fault mode. The boost converter is controlled by a variable voltage depending on the operating state of the motor and generator. The main loss of the motor system has the following four categories: motor loss, inverter loss, booster IGBT loss, and boost inductor loss. All of the above losses are voltage-dependent. The system loss can be reduced by the optimized voltage. To improve the overall performance of the voltage control strategy, the voltage control strategy of the boost converter is dynamically adjusted. The busbar voltage is optimized by feeding back the motor running state and transmitting it to the converter in real time. The vehicle results are conducted, and the power at 6500 rpm is increased by approximately 117% (from 71 kW to 155 kW) when the voltage is boosted from 250 V to 450 V. The acceleration performance of the high-speed is enhanced, and the dynamic performance of the vehicle is improved.
