A power supply conversion logic circuit and its implementation method

Abstract

The invention belongs to the technical field of testing and measurement, discloses a power supply conversion logic circuit and an implementation method thereof and relates to an implementation method of a power supply conversion logic circuit. In the scientific research stage of an aircraft, repeated ground bulk part testing and overall testing need to be conducted so as to verify the rationality and effectiveness of the design and the coordination between systems; in the testing process, DC voltage-stabilized sources need to be used for simulating an aerial carrier power supply, an aircraft battery power supply and an aircraft generator power supply and then simulating mutual switching between the power supplies. Switches, relays and other components are utilized and reasonably connected with the DC voltage-stabilized sources to achieve fast switching between different power supply channels, the operation steps of testers are simplified, the influence of human factors on test results is reduced, the time of switching between different power supply channels is shortened, and the test results are more accurate.

Description

technical field [0001] The invention relates to a power supply conversion logic circuit and its implementation method, which belong to the technical field of testing and measurement, and relate to a power supply conversion logic implementation method, which is mainly used in the ground test process to simulate the power transfer process of an aircraft in a real flight state. Background technique [0002] In the scientific research stage of the aircraft, in order to verify the rationality, effectiveness and coordination between the systems, etc., it is necessary to conduct multiple ground component and overall tests. Battery power supply and aircraft generator power supply, and further simulate telemetry external power supply to telemetry internal power supply, aircraft power supply to aircraft battery power supply, and aircraft battery power supply to aircraft generator power supply. The traditional test method is to use multiple switches and toggle the switch according to t...

Problems solved by technology

[0003] 1) Many manual operations make the test process and results susceptible to human factors;

[0004] 2) The consistency of the power transfer process during the test is poor, which is not conducive to the comparative analysis of the test process and test data;

[0005] 3) The operation process is cumbersome and time-consuming, and the simultaneous connection of different power supply channels takes a long time, which is easy to form voltage backfeeding phenomenon, poor safety, and affects the accuracy of test results
