摘要
直升机瞬变电磁系统(HTEM)是一种以直升机为平台的瞬变探测方法.为了解决HTEM供电变换器的高功率、高电压和稳定输出的问题,本文设计了一种新型双变压器与双整流桥结构的串联谐振电路.详细分析了该电路的工作原理和电路模态,并给出了详细的电路仿真参数和仿真结果.通过搭建样机,输入 28 V/100 A,输出功率达到 2 650 W,实现了零电流关断和零电压开通,提高了HTEM的稳定性,验证了该变换器的可行性.
Abstract
Helicopter-borne transient electromagnetic method(HTEM)is a kind of transient detection method based on helicopter.In order to solve the problems of high power,high voltage and stable output of power supply converter for HTEM,a novel series resonant circuit with dual-transformer and dual-rectifier bridge structure is designed,the operat-ing principle and circuit mode of the circuit are analyzed in detail,and the simulation parameters and results of the circuit are given in detail.Through the prototype,the input is 28 V/100 A,the output power is 2 650 W,the zero-cur-rent switching and zero-voltage switching are realized,the stability of HTEM is improved,and the feasibility of the converter is verified.
