METHOD OF CONTROLLING PARAMETERS OF A SECONDARY UNINTERRUPTIBLE POWER SUPPLY Russian patent published in 2019 - IPC G01R19/00 H02J7/34 H02J3/00 

FIELD: measuring equipment.

SUBSTANCE: invention relates to measurement of electrical values, namely to measurement of currents and voltages during testing and testing of uninterrupted power supply sources, and can be used in test benches of spacecrafts. Method consists in that during operation at the consumer the input and output currents and voltages of the secondary uninterruptible power supply are measured only at change of its input or output parameters. Then the first derivative of these signals is determined, on the basis of which, having preliminarily determined the frequency of analog-to-digital conversions, performing the analogue-to-digital conversion of input and output currents and voltages, obtained values are stored and their analysis is performed, based on which the power consumed and supplied to the load is determined and the duration of the transient process is estimated.

EFFECT: technical result when implementing the disclosed solution is to develop a method of monitoring parameters of a secondary uninterruptible power supply during operation thereof in a consumer.
