Abstract

The invention relates to simulation equipment for simulating a PMG (Permanent Magnet Generator) alternating-current power supply. The simulation equipment for verifying the complex electromagnetic working environment of a high-safety flight control system is applied to electromagnetic compatibility of the flight control system and high-fidelity simulation of the PMG alternating-current power supply of power supply input verification. PMG is a permanent magnet generator installed on an engine, can generate power when working together with the engine, and thus is difficult to use in verification of the flight control system. The variable frequency and variable voltage broadband alternating-current power supply simulation equipment comprises a broadband transformer, a broadband inductor, a protective tube and a varistor, meets the test requirement of the flight control system, and completely simulates the characteristics of different working states of the airborne PMG. The broadband range is 1407-2836Hz.

Description

technical field [0001] The invention relates to a simulation device for simulating a PMG AC power supply, which is aimed at verifying the complex electromagnetic working environment of a high-safety flight control system, and is applied to high-fidelity simulation of the PMG AC power supply for verification of electromagnetic compatibility and power input of the flight control system. Background technique [0002] PMG is a permanent magnet generator installed on the engine, which supplies power to the flight control system to provide high-security system power supply. Since the power supply can only be generated by working with the engine, it is difficult to use it in the verification of the flight control system. Therefore, a high-simulation PMG AC power supply simulation device is needed to meet the test needs. [0003] In order to ensure that the high-safety flight control electronics can meet the functional performance requirements of the technical specifications of the ...
