Publication number: 20150124508Abstract: A low-power power supply for an electronic circuit uses an existing current input and converts the current to a higher voltage sufficient for supplying an electronic circuit. The input current generates a defined input voltage, which input voltage is initially generated by voltage drop by the input current passing at least one diode in the open direction of the diode. The input voltage, through a transistor, charges a plurality of switched capacitor networks in a first mode of operation, and in a second mode of operation, the switched capacitor networks are coupled in series for multiplying the input voltage to second higher voltage that is supplied to a oscillating circuit. The oscillating circuit drives the input current via a transformer and half bridge driver to convert a low voltage current supply from a low voltage current into a low current and higher voltage useable for supplying a small electronic circuit.Type: ApplicationFiled: April 11, 2013Publication date: May 7, 2015Inventors: Mads Kolding Nielsen, Stig Lindemann

Publication number: 20030169546Abstract: The invention relates to an electronic circuit for supplying and protecting another consuming circuit against undesirably high electrical values. The supply circuit is formed with at least 2 independent monitoring circuits performing independent measurement of an error state on the basis of a common threshold value generated from a value determined in the circuit. Recording of an error state in a monitoring circuit results in activation of at least one independent current path between the supply potential of the supply circuit and an associated reference value. This ensures that the electrical circuit increases the current through a separator circuit, which, after activation, isolates the consuming circuit from the remaining circuit. Also, the same reference value may be used for several monitoring circuits whereby tolerance deviations for components may be compensated so that a supply voltage and a safety voltage have values with a small difference.Type: ApplicationFiled: March 11, 2003Publication date: September 11, 2003Inventors: Stig Lindemann, Gade Knud Nielsen

Patent number: 6617988Abstract: A method and apparatus for generating second pulse signal from a first pulse signal. The second pulse signal has flanks positioned with a well-defined spacing. The width of the pulses as well as the frequency and phase correspond to the first signal. The apparatus employs a shape generator for generating a shape signal having uniform and well-defined flanks. A frequency generator produces a clock signal wherein the clock and phase correspond to the first pulse signal. The signal generator produces a second pulse signal from the clock signal and the shape signal for use in restoring distorted digital signals to ensure accuracy and signal integrity.Type: GrantFiled: March 22, 2002Date of Patent: September 9, 2003Assignee: PR Electronics A/SInventor: Stig Lindemann
