POWER CONTROL SIMULATOR heat flux for testing of spacecraft

摘要

The invention relates to test equipment. The technical result is to increase the accuracy of maintaining power to the heating element by compensating for temperature and time drift on the chip, used for generating a signal proportional to the power allocated to the load, and the combination of control functions, power reference and comparison, the same controller. It is achieved by the proposed controller electric power of the simulator heat flux, which comprises a source of alternating current connected to the heating element through a key regulator for controlled valves, driver controller key regulator according to the result of comparison of the signal power with a driving signal, a signal detector, proportional current and voltage of the heating element, the outputs of which are connected to the multiplier for computing a signal proportional to the power provided on the E kroskheme, through the filter and multiplier connected to the first input of the controller associated with the synchronization circuit with the AC source and the phase comprising the pulse width modulator. Thus introduced feedback from the output of the multiplier, formed key associated via series connected amplifier and a first analog-to-digital converter, the second input of the controller, said switch being controlled by the controller to trigger it at the closing state of the valve key regulator, moreover, said the controller includes a program of research and support capacity in the minimum value of these moments, and its output, through digital-to-analog converter and a second amplifier, Port Inonu with zero input adjustment multiplier chip. 1 yl.
