Abstract
A device for connecting in series between a source of alternating current power and a direct current load which decouples the power flow from the source to the load and thereby enables efficient modification of the current waveform supplied by the source to reduce current harmonics, improve the current form factor and improve the power factor. Particular uses for the device include battery chargers, off-line switching power supplies as used by computers, electronic ballasts for fluorescent tubes and variable speed electric motor controls.
