|
摘要
电磁发射机是瞬变电磁(TEM)探测系统的重要组成部分,在航空瞬变电磁法中,针对飞机电源供电能力不足的问题,基于Vicor电源模块串并联技术,设计一种大功率直流电源,与超级电容储能器一起,提高了电源的瞬时功率和供电电压,解决了飞机电源和发射机之间的功率和阻抗匹配问题。实际应用结果表明,该系统具有6.4 kW的平均功率,可以提供超过40 kW的瞬时功率,完全能够满足设计要求。
Electromagnetic transmitter is an important component of transient electromagnetic(TEM)detection system. In order to improve power supply capacity of aircraft using aviation transient electromagnetic method,a high-power DC power supply was designed on the basis of series and parallel technologies of Vicor power supply module,which can raise the instantaneous power and power supply voltage of the power supply in combination with super capacitor energy storage device,and solve the problem of power and impedance matching between aircraft power supply and transmitter. The practical application results show that the system possesses the average power of 6.4 kW,and can provide instantaneous power above 40 kW,which is able to meet the design requirements.
