VOLTAGE REGULATOR Russian patent published in 2009 - IPC G05F1/30 H02M5/12 

FIELD: electricity.

SUBSTANCE: voltage regulator model proposed is an invention referring to the sphere of electrical engineering. Device contains input and output terminals, a sensor of input main voltage and a transformer, the latter's primary coil connected to the first diagonal of a bridge circuit composed of four normally open adjustable alternating current switches; the transformer secondary coil is serially connected to the load circuit with an adjustable alternating current switch connected parallel to it. The control alternating current switches are controlled via three-position comparator units. There are time delay elements inserted in the "more" and "less" control output signals circuit of the three-position comparator unit that enable synchronisation of the transformer primary coil connection and secondary coil bridging with the upper and the lower voltage setup units connected to the "Higher Voltage" and the "Lower Voltage" outputs of the three-position comparator unit accordingly.

EFFECT: simplification of design combined with extension of functional capabilities, minimisation of weight and overall dimensions, rejection of noise generated by the device and maintenance of the consumer end voltage harmonicity under major supply voltage fluctuations.
