METHOD FOR NO-BREAK POWER SUPPLY TO USERS OF POWER SYSTEM OPERATING WITH UNSTABLE ENERGY SOURCES Russian patent published in 2006 - IPC H02J3/28 H02H9/00 

FIELD: power engineering; power supply to users.

SUBSTANCE: proposed method for no-break power supply includes conversion of unstable source energy into AC power and storage of the latter in storage device, voltage frequency of supply mains being regulated by means of adjustable capacitor matrix with bidirectional switches whose capacitor ratings are chosen from ratio of 8-4-2-1 controlled by analog-to-digital phase-frequency AFC circuit of supply mains to frequency of commercial-frequency reference generator; amplitude is regulated by modulating supply frequency with aid of pulse-width modulator; capacitor matrix and supply mains are switched over to DC power supply by means of two thyristor switching bridges whose diagonally opposite DC terminals are connected to storage device through transistor controlled by pulse-width modulator; diagonally opposite terminals of AC bridges are connected to AC supply mains and to capacitor matrix, respectively.

EFFECT: enlarged range of unstable-source useful power capacities at high use factor of their energy, reduced capacitance of storage device.
