Abstract
This invention relates to switching amplifiers and switching power converters with bipolar outputs. A new circuit configuration is disclosed which is neither ‘single ended’ nor ‘bridged’. This introduces a new category of amplifiers and power converters, which are ‘spanning’. Also disclosed are new circuit topologies and new switching sequence strategies for such amplifiers and converters. These unlock improvements in power efficiency, space efficiency and cost efficiency. The improvements can be obtained across a wide range of signal amplitudes, with load circuits which may be resistive, partly reactive, or wholly reactive.
