FIELD: electrical engineering; power regulating and converting devices, such as secondary power supplies, current and voltage converters, automatic-control and computing devices. SUBSTANCE: voltage converter has power amplifier, rectifier unit with filter, and control circuit; in addition, it is provided with isolating unit that makes it possible to isolate power amplifier from control circuit. Power amplifier is supplied with power from external power supply and control circuit, from output rectifier with filter. Such isolation makes it possible to instantly de-energize control circuit and power amplifier in case of overloads and short circuits at output. EFFECT: improved reliability of converter and reduced size. |
