FIELD: electrical engineering.
SUBSTANCE: invention pertains to electrical engineering, particularly to sources of secondary electrical power supply for a radio electronic apparatus. The power supply has a stabilised converter and a pulse-type voltage stabiliser. The latter is connected to an extra rectifier (18) with partial modulation, allowing for lowering overall losses and losses in switch (12) of the stabiliser with arbitrary voltage at the output of the stabiliser.
EFFECT: increased efficiency, reliability, wider functional capabilities.
