Latest Patents
One of Donald's latest inventions is the "Power output stage for switching inductive loads with reduced radiation emission." This invention features a series circuit that includes a load and a switching transistor. A well-designed circuit with a blocking diode and a series of Zener diodes is placed between the drain and gate electrodes of the switching transistor. Additionally, a capacitor, resistor, or a combination of both is situated in parallel with at least one of the Zener diodes. This innovative configuration effectively addresses the pronounced kink in the drain voltage when Zener protection is activated during the switching transistor's operation.
Another notable patent is the "Circuit arrangement for controlling a load and for recognizing a line." This circuit arrangement is instrumental in managing a load by identifying interruptions in the line connected to it. It incorporates a measuring resistance in series with the load, a device for varying the resistance of this measuring resistance based on the current flow, and a diagnostic system that generates a report if the voltage drop across the measuring resistance falls below a predetermined threshold.
