  • Patent number: 11929742
    Abstract: An electronic component is switched under the control of a pulse-width modulation signal. The electronic component outputs an output signal that is controlled by a control signal. The switching on or off is initiated within a pulse-width modulation cycle period at a level change time by a change of the pulse-width modulation signal. The control signal is set within each PWM cycle period to a first control value between the level change time and a first switching time, to a second control value between the first switching time and a second switching time, and to a third control value from the second switching time until a final gate-voltage value is reached on the gate of the electronic component. Each switching time of a PWM period is determined in dependence on an amplitude value determined during a preceding PWM cycle period, to limit amplitudes of the oscillation of the output signal.

  • Publication number: 20230261648
    Abstract: The disclosure relates to a method for switching power transistors in a power transistor circuit. The power transistors each have a gate, which is driven sequentially by at least three control values in the case of a switch-on sequence and/or a switch-off sequence. A switchover occurs between the control values at specific times. The specific times are determined or modified by a controller, which is driven by a Miller plateau detector for detecting a Miller plateau in a gate-source voltage of the respective power transistor.

  • Patent number: 10205382
    Abstract: A method for adapting a dead time between the beginning of ab opening process of a first switching element and the beginning of a closing process of a second, serially connected switching element in a switching regulator of a switching power supply unit. The method includes the following steps: a measurement voltage across the second switching element is measured, and the dead time is varied such that the deviation of the measured measurement voltage from a target value of the measurement voltage is minimized or limited. The first and second switching elements are actuated using the thus ascertained dead time. There is also described a device for carrying out such a method. The device includes a measuring unit, a processing unit, and a control unit.
