The main benefit of self-driven is that the driving circuit is simplified, which results in a low cost solution. However, in conventional buck converter, which is the dominant member in 12V VRM family, it is very difficult to adopt selfdriven scheme. The proposed self-driven topologies are basically buck-derived multi-phase interleaving soft switching topologies, which ca...Mon, 03 Sep 2012 08:20:56 GMTvtippatents@vtip.orghttp://vtip.technologypublisher.com/technology/10202Matrix-Transformer Phase-Shift Buck Converterhttp://vtip.technologypublisher.com/technology/10199This voltage regulator module (VRM) technology enables reduced switching losses and provides a more cost effective approach to achieving high efficiency than a buck converter.6,757,184 (02.122) Mon, 03 Sep 2012 08:20:52 GMTvtippatents@vtip.orghttp://vtip.technologypublisher.com/technology/10199Sensor Based on Producing Long Thin Holes in Optical Fibershttp://vtip.technologypublisher.com/technology/10196Mon, 03 Sep 2012 08:20:50 GMTvtippatents@vtip.orghttp://vtip.technologypublisher.com/technology/10196Biologically Self-Assembled Micro and Macrostructure Ceramics, Metals and Polymer Materialshttp://vtip.technologypublisher.com/technology/10195Mon, 03 Sep 2012 08:20:49 GMTvtippatents@vtip.orghttp://vtip.technologypublisher.com/technology/10195Zero-Voltage-Switch Full Bridge with Self-Drivenhttp://vtip.technologypublisher.com/technology/10193 This invention proposes a high frequency and high efficiency topology. Compared to conventional phase-shift full bridge, the topology is the same and the only difference is the control strategy. Based on the control strategy, Zero-voltage-switch (ZVS) can be achieved. Another benefit from the control strategy is that the gate signal for synchronous rectifier can be derived from the center points of bridge legs directly and easily. Compared to the conventional self-driven, the proposed self-driven does not have severe ringing and the waveform is pretty clean.

Potential applications include electro-optic modulators and frequency doubling devices. The materials and processing steps used result in high degree of non-centrosymmetry in the film, thus forming high net polar ordering which is very useful for various electro-optical applications. Compared to existing electro-optic modulators, this innovation offers advantages, including, higher nonlinear susceptibilities, high modulation rates, and lower device fabrication costs.Mon, 03 Sep 2012 08:20:33 GMTvtippatents@vtip.orghttp://vtip.technologypublisher.com/technology/10182ETO-Based DC Circuit Breakerhttp://vtip.technologypublisher.com/technology/10181Mon, 03 Sep 2012 08:20:31 GMTvtippatents@vtip.orghttp://vtip.technologypublisher.com/technology/10181Converter Topologies for Multiple Energy Sources Power Conversionshttp://vtip.technologypublisher.com/technology/10177Mon, 03 Sep 2012 08:20:25 GMTvtippatents@vtip.orghttp://vtip.technologypublisher.com/technology/10177A Fourpoint Antennahttp://vtip.technologypublisher.com/technology/10174Mon, 03 Sep 2012 08:20:21 GMTvtippatents@vtip.orghttp://vtip.technologypublisher.com/technology/10174Avian Hepatitis E Virus (avian HEV) and Its Uses Thereofhttp://vtip.technologypublisher.com/technology/10173Mon, 03 Sep 2012 08:20:20 GMTvtippatents@vtip.orghttp://vtip.technologypublisher.com/technology/10173Active/Passive Device for Vibrational and Sound Radiation Controlhttp://vtip.technologypublisher.com/technology/10169Mon, 03 Sep 2012 08:20:02 GMTvtippatents@vtip.orghttp://vtip.technologypublisher.com/technology/10169A Start-up Circuit and Control for Isolated Boost DC/DC Convertershttp://vtip.technologypublisher.com/technology/9918Mon, 06 Aug 2012 10:26:14 GMTvtippatents@vtip.orghttp://vtip.technologypublisher.com/technology/9918An Accelerated Commutation for Passive-Clamped Isolated Boost Convertershttp://vtip.technologypublisher.com/technology/9917Mon, 06 Aug 2012 10:26:13 GMTvtippatents@vtip.orghttp://vtip.technologypublisher.com/technology/9917Antimicrobial Compounds to Inhibit Plant Diseaseshttp://vtip.technologypublisher.com/technology/9910Mon, 06 Aug 2012 10:26:03 GMTvtippatents@vtip.orghttp://vtip.technologypublisher.com/technology/9910Continuous Dimming Electronic Ballast with Constant Lamp Power Controlhttp://vtip.technologypublisher.com/technology/9157Thu, 29 Mar 2012 07:36:46 GMTvtippatents@vtip.orghttp://vtip.technologypublisher.com/technology/9157New Gas Discharge Lamp Inverter with a Wide Input Voltage Rangehttp://vtip.technologypublisher.com/technology/9156A novel electronic ballast which can achieve low line input current harmonics, low crest factor constant lamp power, low DC bus voltage stress, and low switching current stress over a wide range of line input voltages.Thu, 29 Mar 2012 07:36:43 GMTvtippatents@vtip.orghttp://vtip.technologypublisher.com/technology/9156
