COMPLEX LOAD SIMULATION TEST OF POWER SPACECRAFT

摘要

The complex load simulation for testing electrical systems spacecraft relates to devices for testing electrical systems. In particular, the invention relates to an electronic simulators for load testing of spacecraft power systems (SES SC). For testing of such systems is necessary to simulate the load in the full range from idle to rated. In order to evaluate the dynamic properties SEP SC, it must be checked under dynamic stress type reset / impingement and to update the output resistance - test at harmonic load over a wide frequency range (up to 30 MHz). Target Utility Model - an increase of energy saving and reduction of mass and size of the input filter by implementing a low-frequency sinusoidal load using a boost converter included in a complex. Complex loading simulation test spacecraft electrical systems comprising several loading modules connected in parallel to the power system under test, and a complex control unit, to which can be a programmable controller or PC. For solutions sinusoidal load module task is divided into two sections: a section of high load and this section of the low-frequency loads, the section of the low-frequency load is executed using said boost converter, which control unit boost converter through sinusoidal load control unit connected to the generator sinusoidal signal included in The module sinusoidal load. High frequency sinusoidal load section is formed as a transistor amplifier operating in emitter-follower mode, with a fixed load, sinusoidal signals controlled oscillator sinusoidal signal constituting the sinusoidal load control circuit.
