摘　　要：为探究被动补偿式外转子永磁脉冲发电机(ORPMPCPA)的放电特性,在综合考虑放电过程中被动补偿作用对电枢绕组电感的影响以及机电能量转换造成转速变化等因素的基础上,建立ORPMPCPA对负载放电的数学模型,对ORPMPCPA放电时的脉冲电流形成过程、能量转化过程以及相关因素对脉冲电流波形的影响进行仿真分析。结果表明,ORPMPCPA能在瞬间将转子内部储存的动能转化为强脉冲电能,且通过改变外电路中触发延迟角、两相绕组组合方式和外接电感数值,实现对脉冲电流波形的灵活调节。通过对比分析样机测试结果和仿真结果,证明所提出的ORPMPCPA放电特性分析方法的准确性。In order to clarify the discharge characteristics of outer rotor permanent magnet passively compensated pulsed alternator(ORPMPCPA), the influence of passive compensation on the inductance of armature winding was taken into account, the change in the rotating speed due to the electromechanical energy conversion was considered, and thus the discharge mathematical model of ORPMPCPA for the load was established. The forming process of pulse current and conversion process of energy as well as the influence of relative factors on the pulse current waveform of ORPMPCPA were simulated and analyzed. The simulated results reveal that under the working condition, the kinetic energy stored in the rotor can be instantaneously transformed into the strong pulse electric energy, and the pulse discharge current waveform can be flexibly adjusted through changing the trigger angle,two-phase winding combination mode and external inductance value. Through comparing the experimental results of the prototype and the simulation results, the accuracy of the proposed analysis method for the discharge characteristics is proved.
