A recently granted patent (Publication Number: US11929742B2) discloses a method for switching an electronic component on or off using a pulse-width-modulation signal. The method involves initiating the switching within a clock period, calculating amplitude magnitudes of the output signal, adjusting control values, and determining switchover instants based on the amplitude magnitude to limit oscillation amplitudes. The patent also includes a control device with oscillation detectors, a control unit, and a signal generator to implement the method effectively. Additionally, closed-loop control circuits are utilized to control switchover instants and the control signal based on amplitude magnitudes, ensuring efficient operation and reduced electrical oscillations in resonant electric circuits.

Furthermore, the patent details a method for repeatedly switching an electronic component on and off in successive time intervals, calculating amplitude magnitudes, adjusting control values, and determining switchover instants based on the calculated amplitudes. The control device described in the patent includes oscillation detectors, control units, signal generators, and closed-loop control circuits to effectively switch the electronic component on or off using pulse-width-modulation signals. By implementing the disclosed methods and control devices, the patent aims to reduce electrical oscillations in resonant electric circuits, providing a more stable and controlled operation for electronic components controlled by control signals.
