  • Patent number: 9906131
    Abstract: A switched-mode power converter includes timing control feedback loop circuits to minimize or eliminate the potential difference across a high-power switch and a low-power switch during their transitions times. A first feedback circuit compares the measured voltage across the high-power switch at the moment the high-power switch closes with the input voltage to the high-power switch to control a low-to-high delay time. A second feedback circuit compares the measured voltage across the low-power switch at the moment the low-power switch closes with the input voltage to the low-power switch to control a high-to-low delay time. A third feedback circuit compares the measured voltage across the low-power switch at the moment the low-power switch opens. The output of the third feedback circuit is provided as inputs to the first and second feedback circuits. The third feedback circuit also controls the frequency of the power converter.

  • Patent number: 9847718
    Abstract: A DC-DC power converter includes a switched inductor power converter and a parallel linear voltage regulator. Two transistors are positioned in the switched inductor power converter to periodically set a bridge voltage thereby producing a square wave with a fixed frequency and variable duty cycle. An inductor and an output capacitor filter the bridge voltage so that only the average value of the bridge voltage is passed to the load. Parasitic impedance due to physical separation of the switched inductor power converter and the load is overcome by providing the parallel linear regulator with its own dedicated channel to the load.

  • Patent number: 9679958
    Abstract: Methods of manufacture of integrated multi-layer magnetic films for use in passive devices in microelectronic applications. Soft ferromagnetic materials exhibiting high permeability and low coercivity are laminated together with insulating layers interposed. Electrical conductors coupled to interconnects are magnetically coupled to magnetic film layers to engender an inductor (self and mutual). Soft ferromagnetic materials are provided in an alternating array of parallel plate capacitors. Each alternating magnetic film is electrically coupled to either a primary or secondary electrical conductor interconnects and separated by an electrically insulating dielectric material. Alternatively, each alternating magnetic layer comprises an induced anisotropy material, which can also be combined with coiled conductor giving rise to a hybrid inductive/capacitive device. Also, soft ferromagnetic material are also selected and tuned to provide for FMR notch filtering.

  • Patent number: 6915798
    Abstract: The flexible exothermic medium of this invention is composed of an exothermic agent which generates heat in contact with air, and a water-absorptive polymer and/or a second polymer other than the water absorptive polymer. The mixture thereof is pressed at a pressure of 100-8000 kg/cm2 with alcohol, a cross-linking agent or a plasticizer. This results in producing flexible united mediums. The flexibility of the exothermic medium is also obtained by irradiating it with light or heating the mixture. The exothermic medium thus prepared is so flexible as to fit any curved part the body and has excellent exothermic characteristics compared with the prior art. The heating element using these exothermic mediums is fit for various uses such as thermotherapy, body warmers, cosmetics and the like.
