With a total of 2 patents to his name, Siepmann's work reflects a commitment to innovation and practical solutions in electrical systems.

Latest Patents

One of Siepmann's latest patents is a fault current protection switch. This device is designed to detect fault currents from conductors of a supply means to ground. The system employs at least one difference transformer connected to the conductors of the supply mains. An oscillation generator circuit is linked to the difference transformer through feedback windings. This circuit checks the magnetization of the core of the difference transformer. In the event of a change in the transforming properties of the core due to mis-magnetization caused by a fault current, the oscillation generator circuit triggers a control and switching member connected in the supply mains to disconnect the same.

Another significant patent is a circuit arrangement for a DC to DC converter. This arrangement includes at least one switching transistor and one transformer. The transformer features a primary winding connected in the collector circuit of the transistor and a secondary winding from which at least one stabilized DC voltage can be tapped via rectifiers. The switching transistor is actuated and blocked by a control component based on load conditions. A voltage comparison device is included to compare the collector-emitted voltage of the switching transistor with a predetermined reference value. Upon overshoot of the reference voltage, the collector-emitter voltage is analyzed to disconnect the base current of the switching transistor.
