Title:
POWER TRANSFER DEVICES, METHODS, AND SYSTEMS WITH CROWBAR SWITCH SHUNTING ENERGY-TRANSFER REACTANCE
Document Type and Number:
WIPO Patent Application WO/2011/008567
Kind Code:
A3
Abstract:
The present application discloses methods, circuits and systems for power conversion, using a universal multiport architecture. When a transient appears on the power input (which can be, for example, polyphase AC), the input and output switches are opened, and a crowbar switch shunts the inductance which is used for energy transfer. This prevents this inductance from creating an overvoltage when it is disconnected from outside lines.
