摘要： The present invention relates to a DC/DC converter of half-bridge type with soft switching comprising a transformer. The primary of the converter is of the type with half-bridge arrangement and is linked to an input voltage source by way of two switches and the secondary is of half-wave type and is linked to a load by means of an inductance. Means are provided for alternately controlling the two switches, at fixed frequency, by pulse width modulation. To reduce the number of components of the converter, a capacitor of small value is arranged in series with said primary winding, which capacitor referred back to the secondary is designed to resonate with said inductance. The inductance is the transformer's leakage inductance seen from the secondary. The switches are advantageously switched while the current in said inductance is not zero.

摘要： An adapter for a multiple operating mode monitor automatically controls the horizontal and vertical deflection circuits of the monitor cathode ray tube depending upon the characteristics of the video source to which the monitor is connected. The adapter has a digital memory for storing sets of monitor operating parameters for each of a plurality of predetermined operating modes at selectively addressable locations. A processor evaluates horizontal and vertical synchronizing signals from a video source to which the monitor is connected to identify one of the plurality of predetermined operating modes corresponding to the synchronizing signals. The operating mode may be evaluated and identified by measuring the period of the horizontal and vertical synchronizing signals form the video source. The memory location corresponding to the identified mode of operation is selectively addressed, the selected set of operating parameters, which may be in parallel format, being available as an output to a plurality of dynamic digital to analog converters. The digital to analog converters, which may be synchronized with the vertical frequency, provide analog control signals for the horizontal and vertical deflection circuits. The horizontal and vertical deflection circuits are adjusted responsive to the analog control signals to correspond to the selected set of operating parameters. The operating parameters may include horizontal and vertical frequency, horizontal and vertical amplitude, horizontal and vertical deflection phase position, brightness and contrast.

摘要： A method of supplying optimal power for an alternating current electric motor driven by a direct/alternating and alternating/direct/alternating static frequency converter including a device for implementing the method. In particular, the method supplies optimal power for an inductive-type load coupled to an application with the load being driven by a static converter controlled by an electronic module. The method involves delivering power to the load by setting parameters which are applied to the controls of the converter and by noting the direction of variation around an extreme, corresponding to a minimum power absorbed by the load on the basis of one or more monitoring parameters which are weighted and/or combined together.

摘要： In a display device images are reproduced by controlling the amount of light provided by a light source by means of light modulators for individual pixels. Subsequent images are synchronised to each other by synchronisation signals regularly occurring at intervals corresponding to first time periods. The backlight is controlled to emit light during fractions of second time periods or whole second time periods which are equal to or shorter than first time periods. Several of the second time periods may be nested and evenly distributed within the first time period. The signals for driving the backlight are preferably generated in synchronism with the horizontal pixel clock. Each of the fractions of second time periods or whole second time periods during which light is emitted is divided into a number of elementary steps, wherein each elementary step corresponds to a number of pixel clock periods. The number of elementary steps is chosen according to the desired ratio of control of the backlight or contrast ratio, e.g. 100 elementary steps for a contrast ratio of 1:100. During each of the second time periods the backlight is controlled to be on for a number of elementary steps corresponding to the desired contrast ratio.
