摘要
The change of discharge circuit parameters will affect the reconnection electromagnetic emission efficiency. This paper simulates and analyzes the influence of capacitor voltage changes on efficiency when the capacitance is 400µF, 600µF, and 800µF. The results show that: first, keeping the capacitance unchanged, the efficiency will first increase and then decrease with the increase of the voltage, and there is an optimal voltage to make the efficiency the highest. Secondly, when the capacitance is 400µF, the efficiency is the highest when the voltage is 20kv; when the capacitance is 600µF, the efficiency is the highest when the voltage is 15kv; when the capacitance is 800µF, the efficiency is the highest when the voltage is 10kv. Finally, the overall efficiency at 400µF is greater, but there will be a large deceleration force in the later stage of the launch, which will reduce the exit speed, resulting in lower efficiency. In this paper, taking the case of 400µF and 10kv as an example, an improved pulse discharge circuit is used to reduce the influence of the deceleration force, which increases the efficiency by 2.79%, and recovers the energy of the original discharge capacitor 52%.
