Embodiment Construction

[0058] The explanations of various inventions in this application are described with particular reference to the current preferred embodiments (as examples, not limitations). This application describes several inventions, and none of the following descriptions should generally be regarded as limiting the claims.

[0059] This application discloses power converters that are usually a buck-boost family, but only use capacitors. The capacitors are either just parasitic capacitors or have additional discrete components that are connected in parallel with a buck-boost inductor to achieve The low turn-off switching stress (ie, "soft switching") of semiconductor switches allows the use of relatively slow and inexpensive switches. In the disclosed alternative embodiments, as discussed below, operation without such external capacitors is possible at the expense of higher forward turn-off conversion losses.

[0060] in figure 1 And in the various other embodiments disclosed, despite the use...

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.

Description

[0001] cross reference [0002] Priority is claimed by both U.S. application 61 / 221,345 filed on 6 / 29 / 2009 and U.S. application 61 / 234,373 filed on 8 / 17 / 2009. The priority is from the U.S. application 12 / 749,207 filed on 6 / 5 / 2009 and now published as US2010 / 0067272, which goes back to the U.S. application 11 / 759,006 filed on 6 / 6 / 2007 and now published as 7,599,196, and thus It goes back to the claim by the US application 60 / 811,191 filed on 6 / 6 / 2006. Priority is also claimed by U.S. application 11 / 758,970 filed on 6 / 6 / 2007, and from this to U.S. application 60 / 811,191 filed on 6 / 6 / 2006. All these applications are hereby included for reference. Background technique [0003] This application relates to power converters, and more particularly to non-resonant power converters that utilize inductance for energy transfer. [0004] Please note: The points discussed below may reflect the hindsight gained from the disclosed invention and may not necessarily be recognized as prior art. [00...
