Resonant dual-power-supply aircraft electromagnetic transmission device

Abstract

The invention discloses a resonant dual-power-supply aircraft electromagnetic transmission device. A high-power main circuit module comprises an alternating-current generator set, a direct-current onboard power supply, a power-conversion main circuit, a resonant main circuit and a transmitter circuit; the alternating-current generator set and the direct-current onboard power supply are in parallel connection with the power-conversion main circuit, the power-conversion main circuit converts onboard power supply direct current or generator set alternating current into high-frequency alternating current through a high-frequency inverter bridge or a controllable rectifier bridge-high-frequency inverter bridge, the high-frequency alternating current is converted into direct current through a high-frequency uncontrolled rectifier bridge, and the direct current is inverted into alternating-current square waves through half-bridge inverter; the power-conversion main circuit is connected with the resonant main circuit, and the resonant main circuit converts the alternating-current square waves into sine waves with a constant resonant frequency; and the resonant main circuit is connected with the transmitter circuit, and the transmitter circuit transmits required electromagnetic waves with a transmission frequency and a waveform. The resonant dual-power-supply aircraft electromagnetic transmission device reduces the capacity, hoisting weight and size of a hoisting alternating-current generator by utilizing a parallel power supply manner.

Description

technical field [0001] The invention relates to the technical field of aeronautical electromagnetic prospecting, in particular to a time-domain resonant double-power-supplied large magnetic moment aeronautical electromagnetic launching device. Background technique [0002] At present, with the rapid development of my country's economy, people's demand for mineral resources continues to increase. In areas with relatively good terrain conditions in China, the exploration of mineral resources has been basically completed. However, the central and western regions, which account for more than 65% of my country's land area, are rich in mineral resources, but their terrain conditions are extremely harsh, making it impossible for personnel to carry out exploration work on the ground, resulting in the rich mineral resources contained in them. mining. In order to solve this problem, people gradually turn their attention to the airborne electromagnetic prospecting method (AEM) for the...

Problems solved by technology

However, as the power of the electromagnetic launcher increases, the weight and volume of the launcher will also increase; limited by the space and weight of the flight platform, the weight and volume of the launcher cannot increase infinitely

[0005] At present, the existing aeronautical electromagnetic launch devices either only rely on the DC airborne power supply for power supply, or only rely on the hoisting AC generator set for power supply, and have not realized the maximum utilization of power.
