Patent number: 9214864Abstract: A switch mode power supply has a first and second branch of an inductive element; a first switching element and a second switching element connected in series. Both branches are coupled to a power source in parallel. A controller controls said switching elements for operating said switch mode power supply in a plurality of consecutive time periods, wherein more than two of said switching elements are closed, i.e. at least one in each branch. The power supply has a polarity switching element coupled between said branches for receiving a pulsed voltage for providing an output voltage of a switchable polarity. The controller receives a feedback signal corresponding to the output voltage, compares the feedback signal to a reference waveform, and controls said switching elements and the polarity switching element in dependence of said comparing for generating the output voltage according to the reference waveform.Type: GrantFiled: April 26, 2012Date of Patent: December 15, 2015Assignee: Freescale Semiconductor, Inc.Inventors: Beatrice Bernoux, Josef Drobnik
