MICROENERGY CONVERTER OF UNIPOLAR VOLTAGE INTO BIPOLAR Russian patent published in 2012 - IPC G05F1/585 

FIELD: electricity.

SUBSTANCE: microenergy converter of unipolar voltage into bipolar one is proposed, comprising an input voltage divider from serially connected first and second resistors, an operational amplifier, the inverting input of which is connected with the middle point of the divider, and also with an output of the operational amplifier via the third resistor, and the output of the operational amplifier is connected via an inductor, to the output of the converter, besides, the output of the converter is connected to a non-inverting input of the operational amplifier, and the output of the converter is connected to poles of the input voltage source via the first and second filtering capacitors, at the same time it additionally comprises a logical element-CMOS inverter, at the same time the output of the operational amplifier is connected to the inverter input, and the inverter output is connected to the point of connection of the third resistor and the inductor, at the same time the inverting input of the operational amplifier is connected with the middle point of the divider and the output of the inverter via the third resistor, and the non-inverting input of the operational amplifier is connected to the converter output.

EFFECT: development of a converter of unipolar voltage into bipolar one, which has high efficiency that does not depend on load current, also in microenergy mode of consumption.
