OUTPUT CIRCUIT FOR MAGNETIC/ELECTRONIC TRANSFORMER Russian patent published in 2018 - IPC G01R31/28 H05B41/282 H02M1/14 

FIELD: electricity.

SUBSTANCE: output circuits (1) for receiving output signals from transformers (2) contain filters (11) and switches (12). In case of magnetic/electronic transformers, the filters (11) are activated/deactivated, for example, for performing/not performing the filtration of foreign signals coming from the converters (4). The filters (11) can contain capacitors. The switches (12) may contain fuses. The output signals of the magnetic/electronic transformers contain relatively low/high frequency signals, which result in relatively small/large currents flowing through the capacitors; these currents will cause the fuses to burn out/not burn out. The capacitors, when activated, form, along with the inductance of scattering of magnetic transformers, electromagnetic interference suppression filters. Alternatively, the circuits (1) may further comprise of sensors (13) for detecting the types of transformers and for controlling the switches (12) in response to the detection results. In this case, the sensors (13) can be configured to detect frequency signals in the output signals and comprise of comparison devices (15) to perform the comparison of detection results (14) with the threshold values.

EFFECT: providing power supply from two different types of transformers.
