    摘要: Alteration of voltage input to a voltage regulator output stage from a Vbus regulator stage in a two-stage voltage regulator provides optimal Vbus voltage placement for a wide range of current loads to increase voltage regulator efficiency and is particularly suited to CPUs having power-saving sleep modes of operation. An optimal voltage is selected or developed in response to information concerning operational mode or current consumption of the powered device. As a perfecting feature of one embodiment of the invention in which a discrete Vbus voltage is selected based on operational mode, the selected voltage is adjusted to further optimize the matching of the Vbus voltage placement to the load and provides a continuous range of voltages. In a second embodiment the entire Vbus positioning function is performed in response to current load information. A feed-forward arrangement is provided to avoid transient spikes as the Vbus voltage placement is altered.

    摘要: A power converter having a primary circuit (e.g. full bridge) and a secondary circuit (e.g. current doubler) has switches in the secondary circuit that are controlled by a drive circuit. The drive circuit is connected to a swing node in the primary circuit, and is powered by the swing node. The drive circuit has an isolation device such as a transformer to provide electrical isolation between the primary circuit and secondary circuit. The drive circuit provides a current source for driving the secondary switch gates, thereby reducing power consumption. The present drive circuit provides clean gate drive signals without noise and oscillations. The drive circuits of the invention are simple, and require only a few components.

    摘要: A multiple phase buck converter or boost converter, or buck-boost converter has an inductor in each phase. The inductors are inversely coupled. In a first embodiment, the converter includes a toroidal magnetic core with inductors extending under and over opposite sides of the toroidal magnetic core. The coupled inductors are thereby inversely coupled and have a relatively low ohmic resistance. In a second embodiment, the converter comprises a ladder-shaped magnetic core (i.e. having parallel sides, and connecting rungs). In this case, the inductors extend under the sides, and over the rungs. Each inductor is disposed over a separate rung. The ladder-shaped magnetic core is preferably disposed flat on a circuit board. Inverse coupling and low ohmic resistance are also provided in the second embodiment having the ladder structure.

    摘要: An image is formed on a transfer medium comprising a hydrophilic tackifier. Any portion of the image that is dimensionally insufficient to permanently adhere the image to the receiver substrate is determined, and a colorless liquid ink comprising water is applied to cover and surround the portion of the image that is dimensionally insufficient to permanently adhere the image to the receiver substrate. When heat is applied to the image to transfer the image layer to a receiver substrate, water in the image layer swells the image layer and the hydrophilic tackifier becomes sufficiently tacky to permanently adhere the image to the receiver substrate.

    摘要: A wireless communication system and a method for detecting downlink receiving power in the system are disclosed. N cells in the system respectively transmit data to at least one receiving terminal via N resource blocks using the same time-frequency resources; multiple channel state information reference signals (CSI-RSs) of a corresponding cell are set in each resource block, and orthogonality is maintained among the CSI-RSs of all the cells, wherein N is an integer greater than 1. Said method includes: an additional demodulation reference signal (DM-RS) used for indicating a receiving power is set in a puncture position in the resource block of the first cell which corresponds to a CSI-RS set in a resource block of another cell; and the receiving power of said first cell is detected according to said additional DM-RS. By using said method, the receiving power of a single cell in N cells can be detected, and the system overhead is not increased.
