Title: Jiri Podrapsky: Innovator in Magneto Ignition Systems
Introduction
Jiri Podrapsky is a notable inventor based in Buchschwabach, Germany. He has made significant contributions to the field of ignition systems, particularly in the development of magneto-semiconductor technologies. With a total of 9 patents to his name, Podrapsky's work has had a considerable impact on internal combustion engine applications.
Latest Patents
Among his latest patents is the "Magneto-semiconductor ignition system." This invention aims to suppress negative half-waves derived from a magneto armature, which are not used for ignition without external damping networks. The semiconductor switch controlling current flow is designed as a monolithic semiconductor element. It utilizes the inherent inverse diode of the monolithic element to pass reverse voltage half-waves. To prevent damage from over-voltage or current overloading, a damping resistance element is connected in series with the main current-carrying path of the monolithic circuit elements. This innovative design enhances the reliability and efficiency of ignition systems.
Another significant patent is the "Magneto ignition system for an internal combustion engine." This invention addresses the potential dangers of reverse-direction operation in internal combustion engines, such as those used in chain saws or lawn mowers. A diode is strategically connected across a second ignition instant modifying R/C circuit in the control network of the magneto ignition system. This design ensures immediate conduction of a control transistor, effectively blocking a controlled ignition transistor and disconnecting the ignition system in case of reverse rotation. This system represents a further development of the basic ignition system described in U.S. Pat. No. 4,188,929.
