APPARATUS FOR MONITORING PARAMETERS OF A SECONDARY UNINTERRUPTIBLE POWER SUPPLY Russian patent published in 2019 - IPC G01R19/165 

FIELD: electrical engineering.

SUBSTANCE: device for monitoring parameters of a secondary uninterruptible power supply source comprises a computer connected to a microcontroller, the output of which is connected to a storage device, and the inputs are connected to the analogue-to-digital converter and the voltage-controlled generator, which is connected to the compression unit. Compression unit comprises four differentiating amplifiers, outputs of which are connected to adder, which is connected to generator, controlled voltage, and inputs of differentiating amplifiers are connected to inputs of analogue-to-digital converter and outputs of matching device, to inputs of which are connected input network and output of secondary uninterruptible power supply, which input is connected to input network, and output – to load.

EFFECT: monitoring of electric parameters of the source during its operation at the consumer.
