FIELD: electric energy transformation technologies.
SUBSTANCE: secondary power supply belongs to group of reverse drive transformers with pulse-width modulation based control over stabilization of output voltage. Device contains force transformer (3) with primary winding, accumulating energy from primary source (7), secondary windings for transferring energy to load (4) and creating reverse connection voltage, commutation element (2), current indicator in form of current transformer with active load, generator with pulse duration control input, controlling the open state of commutation element (2), comparison device (5), outputting signals for pulse-width modulated output signals of generator (1) and support voltage element (stabilitron) (12).
EFFECT: ensured serviceability of secondary power supply with stabilization of load voltage in broad range of voltage values of primary supply.
