摘　　要：讨论了一种三相42 V/4 kW汽车感应发电机系统设计方案,以满足未来对车载电源功率的需求。该方案采用一个与感应发电机直接相连的低成本二极管桥式整流器将有功功率传递给蓄电池和负载,感应发电机的励磁电流由一个小功率PWM变换器提供。同时,这里还提出了一种新颖的控制策略来控制发电机的输出电压,它主要通过控制一个辅助的PWM变换器来实现。通过对一辆桑塔纳2000的电路进行改造,在一台42 V/4 kW的实验样机上进行实验,得出此发电机系统在不同发电机转速和不同负载条件下的性能曲线。A three-phase 42 V/4 kW induction-machine-based automotive power generation scheme is discussed to meet the future electrical power demand in automobiles.This scheme uses a low cost diode bridge rectifier which di-rectly connected to the induction machine to transfer active power to the battery and the load.The excitation to the machine is supplied by means of a low power pulse width-modulation（PWM）converter to control the output voltage of the generator.This paper also uses a new control method to regulate the output voltage of the induction generator by con-trolling the auxiliary PWM converter.With reconstructing the circuit of a Santana 2000 and experiment on a 4 kW/42 V prototype,the performance results of the induction generator scheme at various speeds and loads are presented.
