Patent Number Title Of Patent Date Issued
8269532 Constant phase angle control for frequency agile power switching systems September 18, 2012
Power switching systems often benefit from controlling the instant at which the power devices change state so as to minimize dissipation in these devices. Such systems often require fairly tight tolerances on reactive components and a relatively narrow frequency operating range to be
7995362 High voltage full bridge circuit and method for operating the same August 9, 2011
A circuit apparatus for providing an AC voltage to a load. The apparatus may include: a first, second, third and fourth switch, wherein the first switch is connected between a first node and a first terminal of the second switch and the fourth switch is connected between a second node
7906997 Constant phase angle control for frequency agile power switching systems March 15, 2011
Power switching systems often benefit from controlling the instant at which the power devices change state so as to minimize dissipation in these devices. Such systems often require fairly tight tolerances on reactive components and a relatively narrow frequency operating range to be
7787268 Power switching system to increase induction heating to a load from available AC mains power August 31, 2010
In one aspect, the invention provides a power system for providing power to a load. In some embodiment, the system comprises: a rectifier configured to rectify an AC main signal to produce a rectified AC main signal; a zero cross detector configured to receive the AC main signal and
