A resonant dual power supply aviation electromagnetic launcher

Abstract

The invention discloses a resonant double power supply aviation electromagnetic launching device. The high-power main circuit module includes an AC generator set, a DC airborne power supply, a power conversion main circuit, a resonant main circuit and a transmitting circuit; the AC generator set and the DC airborne The power supply is connected in parallel to the main circuit of the power conversion, and the main circuit of the power conversion converts the direct current of the airborne power supply or the alternating current of the generator set into high-frequency alternating current through the high-frequency inverter bridge or controllable rectifier bridge-high-frequency inverter bridge, and the high-frequency alternating current is passed through The high-frequency uncontrolled rectifier bridge is converted into direct current, and the direct current is converted into an AC square wave by the half bridge; the power conversion main circuit is connected with the resonant main circuit, and the resonant main circuit converts the AC square wave into a sine wave with a fixed resonant frequency; the resonant main circuit It is connected with the transmitting circuit, and the electromagnetic wave of the required transmitting frequency and waveform is transmitted through the transmitting circuit. The invention adopts the mode of parallel power supply to reduce the capacity, weight and volume of the hoisting alternator.

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.
