20160141872 | POWER SUPPLY - A power supply and a method for operating the power supply in which a transformer connected to an excitation circuit . . . is adapted to be connected to a power source, which secondary winding is connected to at least one first power supply. From prior art. switch mode power supply based on fly back technology is well known. Here a power supply with a power inlet is provided with a plurality of separated power outlets. One of the lines connected to the primary winding is further connected to a discharge control circuit, which discharge control circuit is further connected to at least one second power supply and the primary winding is further connected to a discharge circuit where at least one further power supply is connected. | 05-19-2016 |
20150200600 | CONVERTER WITH SHARED CURRENT PATH AND ISOLATION BARRIER - A converter with at least one or more transformers having at least one primary side magnetically coupled to at least one secondary side, the primary side being electrically isolated from the secondary side, wherein a first transformer has first and second sets of coils and a second transformer has third and fourth sets of coils. The first set of coils is connected in series to the third set of coils, wherein one of the secondary sides is connectable to an external output unit, wherein another secondary side is connectable to an external input source, wherein the two secondary sides are electrically isolated from each other, wherein the primary side is adapted to drive the transformers that are connectable to an external power source. The converter uses a shared current path and an isolated current-to-current transfer between the input and output sides to replicate the input current to an output current. | 07-16-2015 |
20150138837 | MAGNETIC BALANCED CONVERTER WITH ISOLATION BARRIER - A converter with at least one primary side having a first set of coils magnetically coupled to at least one secondary side having at least a second set of coils, wherein the primary side is electrically isolated from the secondary side by an isolation barrier, wherein one of the secondary sides is configured to be connected to an external output unit, wherein the primary side is magnetically coupled to another secondary side having a third set of coils which coils are configured to be coupled to an external input unit, wherein the two secondary sides are electrically isolated from each other by a second isolation barrier, wherein the three sets of coils are magnetically coupled to each other via a common magnetic path. The converter provides an isolated current-to-current transfer between the input side and the output side which replicates the input current with high accuracy. | 05-21-2015 |
20150116137 | SYSTEM FOR LINEAR INTERPOLATION IN MULTIPLE DIMENSIONS - A system for galvanic isolation between an analog input signal and an analog output signal, which system performs an analog to digital conversion of the input signals into input digital data. As a result, input parameters can be corrected in a nearly perfect way. | 04-30-2015 |
20130077359 | Power Supply and Method of Operation - A switched-mode power supply (SMPS) and a method of control thereof is described, wherein the SMPS is operable to apply a spread spectrum modulation to a switching driver signal to reduce EMI in the SMPS. The SMPS is operable to perform voltage and current monitoring in parallel to the spread spectrum modulation to provide variable limit threshold detection and shutdown capabilities for circuit protection. | 03-28-2013 |
20130076548 | Delta Sigma Modulator - A modulation system and method for a converter system, preferable a Delta Sigma converter, is described. The system is operable to adjust the modulation performed depending on the specified format of the input and output signals for the converter. The feedback and feed forward pulsed may be adjusted depending on the requirements of the converter. | 03-28-2013 |
