TRANSFORMERLESS VOLTAGE CONVERTER Russian patent published in 2014 - IPC H02M7/155 

FIELD: electricity.

SUBSTANCE: voltage converter consists of two identical sections of an excessive voltage blanking unit which are made as an in-series connected capacitor and resistor switched on into two wires respectively between the outputs for connection of the power supply source and the inputs of the first and second bridge rectifiers; the output of the first rectifier is connected in parallel to the input of a voltage stabiliser and in both wires at output of the second rectifier the first and second regulating elements are introduced which are connected in-series to the input of the voltage stabiliser.

EFFECT: reducing value of consumed active power and increasing stability of output voltage.
