FIELD: electrical engineering.
SUBSTANCE: invention pertains to electrical engineering, particularly to critical radio electronic equipment secondary electrical power supply sources. Redundant power supply of DC voltage contains galvanically isolated voltage and power stabilizers, which enable to completely isolate high-voltage and low-voltage circuits, secure people and equipment against electrocution. Higher reliability of redundant power supply consists in application of flyback voltage converter arrangement, which enables to simplify power amplifier scheme. Higher reliability of redundant power supply is also ensured by using control unit simplified layout. Use of galvanically isolated power stabilizer, which protects redundant power supply source against overloads and provides several channels parallel operation, also increases redundant power supply source reliability.
EFFECT: technical result consists in improvement of redundant power supply source reliability and lower probability of people and equipment electrocution.
