Abstract
A circuit to control a switching characteristic of a switching device. The circuit includes a driver circuit comprising an output port, where the driver circuit is configured to generate, at the output port, a control signal to actuate the switching device within a first time period. The control signal comprising at least one electrical pulse, where a pulse width of the at least one electrical pulse being shorter than the first time period. The circuit also includes a coupling circuit that is configured to use the control signal to actuate the switching device to establish a target switching characteristic of the switching device according to a modulation of the at least one electrical pulse. The control circuit is also configured to provide a greater impedance to the control signal than an impedance of the output terminal of the driver circuit.
