分割トポロジ電源アーキテクチャ
Document Type and Number:
Japanese Patent JP2005504500
Kind Code:
A
Abstract:
A power-supply system describing a bi-directional flyback topology comprises two flyback converters working in opposite directions. Current flowing from a power supply unit (101) to an apparatus (102) is converted from a mains input (119) in the power supply unit to a rectified output current fed to the apparatus via a two-lead cable (116). In the opposite direction, a secondary control circuit (120), situated in the apparatus, comprising a secondary switch (115) causes excess current to be fed back to the power-supply unit where primary control circuitry (103) reacts to stabilize the current fed to the apparatus. The primary control circuitry serves to minimize the amount of energy received from the feedback. The excess current in the apparatus is determined by monitoring the voltage and the current in the apparatus is load. If the measured parameters are too high, transfer of more energy back to the power-supply unit will be performed.
