ELECTRIC VALVE Russian patent published in 2012 - IPC H02M7/217 

FIELD: electricity.

SUBSTANCE: electric valve comprises a controlled key and a comparator, the controlled key comprises two controlled elements, every of which has a power output, a control output and a common output, the comparator has two inputs, an output, a common output and supply outputs, controlled elements of the controlled key are connected oppositely in series, for this purpose the common output of the first controlled element and the common output of the second controlled element are connected and form a common circuit of the controlled key, which is connected to the common output of the comparator, at the same time the control output of the first controlled element and the control output of the second controlled element are connected to each other and form a control input of the controlled key, which is connected to the comparator output, the power output of the first controlled element forms an output of an electric valve anode and is connected to one of comparator inputs, the power output of the second controlled element forms an output of an electric valve cathode and is connected to the other input of the comparator, the outputs of the comparator supply form the inputs of the electric valve supply.

EFFECT: increased efficiency factor of a power supply system and reliability due to lower resistance of an electric valve in open condition and reduced dissipated power.
