Title: Innovations of Markus Pfeifer

Introduction

Markus Pfeifer is a notable inventor based in Nuremberg, Germany. He has made significant contributions to the field of semiconductor technology, holding a total of 8 patents. His work focuses on improving the efficiency and reliability of semiconductor switches and power grid operations.

Latest Patents

One of his latest patents is a driver circuit and method for controlling a semiconductor switch. This invention includes a contact for connection to a control terminal of the semiconductor switch and a device to measure a value dependent on the current flowing through the switch during the switch-off process. The measured value can either be the level of the gate current at a specific time or a timespan until a defined threshold voltage drop is reached. Based on this measurement, the device activates control measures to manage the current change over time effectively.

Another significant patent involves a method and switch module for operating a load zone on a power grid. This method captures and stores at least one load profile during the setup operation, documenting the temporal progression of current or voltage in the load zone. A tolerance range for operating parameters is defined based on this profile, allowing for monitoring during normal operation. If the parameters fall outside the tolerance range, the load zone is disconnected from the power grid to ensure safety and reliability.
