HYSTERESIS LOOP RECORDING DEVICE Russian patent published in 2020 - IPC G01R33/14 

FIELD: measurement.

SUBSTANCE: invention relates to magnetic measurements and is intended for recording weber-ampere private hysteresis loops of electrical devices. Hysteresis loops recording device is additionally equipped with constant voltage source, serially connected by resistor and capacitor, microcontroller, power supply based on a full bridge of four transistors, gates of the first pair of full-bridge transistors are connected to the first output of the microcontroller, the second output of which is connected to the gates of the second pair of transistors of the full bridge, input terminals of which are connected to DC voltage source, to output terminals of the bridge there connected are serially connected resistor and capacitor so that outputs of capacitor are also outputs of power supply source, to outputs of which magnetizing winding is connected.

EFFECT: registration of weber-ampere private hysteresis loops, wider field of use of the recording device.
