Appl. No.:

14/397188

Inventors:

Beatrice Bernoux - Tournefeuille, FR
Josef Drobnik - Mesa AZ, US

Assignee:

Freescale Semiconductor, Inc. - Austin TX

International Classification:

H02M 3/158

US Classification:

323271

Abstract:

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.

Appl. No.:

13/835911

Inventors:

Josef C. Drobnik - Mesa AZ, US

Assignee:

Freescale, Inc. - Austin TX

International Classification:

G06F 1/32

US Classification:

713324

Abstract:

A power source delivers power from a main power source using switching by a normally on transistor. A driver switches on and off the normally on transistor under a control signal by a controller during regular operation. A housekeeping power supply delivers auxiliary power to the driver. The driver switches off the normally on transistor during irregular operation. Irregular operation occurs at least when the control signal is absent or no auxiliary power is available or during transients such a power up or down. Bridge block pairs thereof can be arranged to form a half bridge power switch, an H bridge switch, a three phase bridge switch, a multi-phase switch, a buck converter, a buck-boost converter, or a boost converter.
