Title: Neven Pischl: Innovator in Power Coupling Circuits
Introduction
Neven Pischl is a prominent inventor based in Santa Clara, CA (US). He has made significant contributions to the field of power coupling circuits, particularly in applications related to single-pair Ethernet and automotive technologies. With a total of 8 patents to his name, Pischl's work has had a substantial impact on communication interfaces.
Latest Patents
One of Pischl's latest patents is focused on power coupling circuits for single-pair Ethernet with automotive applications. This innovative circuit for power on data line (PoDL) injection includes a power source, a first and a second coupling component, and an interface. The power source provides one or more DC voltage levels, while the first coupling component connects the power source to an interface for coupling to a transmission medium. An Ethernet device is linked through the second coupling component to the interface. Notably, the first coupling component is a balanced component, and the Ethernet device is isolated from the power source via a pair of DC blocking capacitors.
Another significant patent addresses a method and system for mitigating transformer saturation in a communication interface. This method involves detecting changes in impedance due to transformer saturation of isolation transformers in a network path. The network conforms to the IEEE 802.3af specification, allowing power delivery through the network. The method includes generating a pulse at one end of the network and measuring reflections to detect transformer saturation. In response to impedance changes, a transmitter signal may be pre-distorted to compensate for the saturation, or power delivery may be disabled.
