FIELD: electricity.
SUBSTANCE: stabiliser contains main transformer with primary side and two secondary sides, auxiliary transformer with primary and secondary sides, rectifier, bridge measuring element, voltage divider and power amplifier. These elements form two channels of stabiliser: main and auxiliary channels (controlled bootstrap channel). Both channels are interconnected by series connection of load and secondary sides of two transformers so that output voltages of these sides on load are added. On-load voltage in low voltage controlled auxiliary canal is regulated only due to increase or reduction of bootstrap to changed voltage in the main channel.
EFFECT: maintaining form of stabilised voltage and improving reliability of stabiliser operation due to exclusion of high power elements from scheme.
