FIELD: electronics; power supply to computers and systems built around them, especially power units at transformerless rectifier input.
SUBSTANCE: ac supply mains voltage is converted into dc voltage by means of rectifier. Computers and systems built around them are directly supplied with power at this voltage. At the same time this voltage is continuously supplied to electrical energy storage. Upon failure or interruption of power supply dc voltage is directly applied to computers and systems built around them from storage without its further conversion thereby affording no-break power supply.
EFFECT: enhanced reliability of power supply excluding power loss.
