- Abstract
For the large volume and low reliability of power supply switch in traditional aerospace equipment, a high reliability compound switch circuit is proposed, power bus is controlled to switch by controlling the power MOSFET’s gate-to-source voltage with a small relay; the principle of the circuit is analised, and design method of the components is showed; the experiment result indicates that this switch circuit can control the power bus to switch reliable, the inrush current can be reduced more than 90\% by changing the soft capacitor; the circuit has small volume and high reliability. It has been applied in satellite payload power supply, and it can has a wide range of promotional value which can be applied to the fields, such as deep space exploration and manned moonfall.
