Background
At present, the interface of an external power supply controller is mainly used for realizing the interlocking control function with a ground power supply, and the input end adopts a large amount of large resistors for voltage division, so that the circuit cannot be damaged in a short time when abnormal high voltage enters the first interface. The second interface adopts the mode of reverse diode protection to prevent the entering of outside unusual high pressure.

Illustratively, the large voltage in the present invention is 1.5 times or more higher than the normal operating voltage of the system, for example, the voltage signal received by the second port in the embodiment is 28V.
The second isolation module 70 works as follows, when the second light emitting diode D6 is turned on and then emits light, the gate of the second switch tube Q2 is a photosensitive device, and when the second switch tube Q2 receives light and then is turned on, the second voltage 15VDC connected to the second switch tube Q2 passes through the second switch tube Q2, so that the gate voltage of the power switch tube Q0 connected to the second switch tube Q2 is increased.

The E and F interfaces are interlock control circuit interfaces, and the general circuit design is as follows: e and F are designed to be short-circuited on the ground power supply 1 side, and E and F are designed to be electrically isolated on a power supply control circuit of the aircraft. The working principle of the E and F interlocking control circuit is as follows: after the ground power supply 1 is connected with the gun and plugged into an external power socket of the aircraft, the ground power supply 1 is started to generate three-phase alternating current 2 of 115V/400Hz, and a connecting button 5 on the connecting gun is pressed after the ground power supply 1 operates normally, as shown in figure 2, the three-phase alternating current 2 of the ground power supply 1 enters an aircraft power grid through A, B, C and N, and simultaneously the ground power supply 1 outputs 28V direct current which lasts for 500ms and enters the aircraft power grid through E and F.

The advantage of the present invention is that the present invention provides the corresponding first isolation module 10 and second isolation module 70 at the two first ports and second ports of the power control circuit, respectively, so that when high voltage occurs at the first ports and second ports, the output module 50 at the back end is not damaged. On the other hand, the first port needs to output a dc voltage, so the dc voltage cannot pass through the first isolation module 10, and the dc voltage is converted into an ac voltage by converting the dc voltage into an ac voltage, i.e., by the conversion unit 101, and then the ac voltage is converted into a dc voltage by the filtering unit 103 for output.
