摘　　要：为了满足多脉波整流器在多电、全电飞机用电设备方面的需求,提出了一种具有宽范围的可调式自耦升压变压器(ASBT),以实现对电力系统输出电压的调节。根据自耦变压器对于移相结构的要求,通过改变自耦变压器电源接入点,确定了自耦升压变压器的初、次级绕组匝数关系,给出了可调式自耦变压器的升压范围,分析了24脉波整流器的工作原理,并与其他具有升压效果的自耦变压器进行比较,分析了不同升压比时等效容量的变化。理论分析、仿真以及半实物结果表明,该变压器不仅能够实现输出电压宽范围的调节,并且具有等效容量小的优点。In order to meet the requirements of multi-pulse rectifier for multi-electric and all-electric aircraft electrical equipment,an adjustable self-coupling boost transformer(ASBT)with wide range is proposed to adjust the output voltage of power system.According to the requirements of the phase-shifing structure of the autotransformer,the primary and secondary winding turns of the self-coupling boost transformer are determined by changing the access point of the autotransformer power supply,the boost range of the adjustable autotransformer is given,the working principle of the 24-pulse rectifier is analyzed and compared with other boost autotransformers,the variation of equivalent capacity at different boost ratios is analyzed.Theoretical analysis,simulation and hardware-in-the-loop results show that the trans-former can realize wide range of output voltage regulation,and has the advantage of small equivalent capacity.
