Latest Patents
One of Merval's latest patents is a "Progressive start up device for a switching power supply." This invention involves a switching power supply controlled by modulated width pulses, which are obtained through the comparison of a saw-tooth voltage and a servo control voltage. The servo control voltage is initially set to a value outside the oscillation interval of the saw-tooth, allowing for a controlled variation that results in progressively increasing pulse widths.
Another significant patent is the "Line synchronization detection circuit." This invention pertains to a detection circuit for a line synchronization signal in a video signal. The circuit includes a voltage-controlled oscillator that supplies a line scanning signal to a display. It features a detection window related to the oscillations of the VCO and detects the presence of the synchronization signal, enabling or inhibiting the loop based on the detection of synchronization tops.
