Title: Innovations by Andreas Holweck

Introduction

Andreas Holweck is a notable inventor based in Erlangen, Germany. He has made significant contributions to the field of electrical engineering, particularly in the area of power systems for mining excavators and diesel-electric drive systems. With a total of four patents to his name, Holweck's work reflects a commitment to enhancing efficiency and sustainability in industrial applications.

Latest Patents

One of Holweck's latest patents focuses on limiting the peak electrical power drawn by mining excavators. This innovation involves reducing the maximum electrical power drawn from an electrical power source by supplying supplementary electrical power from an energy storage unit. The system is designed to manage the cyclic nature of input electrical power, setting an upper limit to prevent overloads. When the power drawn exceeds this limit, the energy storage unit, such as an ultracapacitor bank, provides additional power. This bank can be charged during off-peak intervals, and power generated during regeneration can also be recaptured and stored.

Another significant patent by Holweck is for a diesel-electric drive system. This system includes a generator with two multi-phase winding systems, a diesel engine, and a DC-link converter. It features self-commuted pulse power converters linked to the winding systems, allowing for a self-load test of the diesel motor's capacity. This design helps eliminate overloads of the power semiconductors, enhancing the reliability of the system.
