FIELD: electrical equipment.
SUBSTANCE: invention relates to the electrical equipment. Versions of devices are designed to produce highly stable constant voltage in wide range of output voltages. Production of highly stable constant voltage is ensured by generating a control signal which varies pulse ratio when converting constant voltage into pulsed voltage, taking into account the constant voltage setting in the load, as well as stabilizing direct current and reducing pulse components in DC composition by using negative feedback.
EFFECT: device for producing constant voltage (versions) is disclosed.
