Title: Clarence D Lilienthal: Innovating Safety in SCR Technology
Introduction
Clarence D Lilienthal, an inventive mind from Eden Prairie, MN, has made significant contributions to the field of silicon controlled rectifiers (SCRs) with his innovative patents. With a total of two patents to his name, Lilienthal's work focuses on enhancing the safety and efficiency of SCR systems.
Latest Patents
Lilienthal's latest innovations include a "System for Detecting Faulty SCRs" and an "SCR Controller Having Input Pulses Mechanically Generated by a Signal." The first patent describes a safety circuit capable of sensing shorted conditions in SCRs, which automatically disconnects the load from the AC mains during a short circuit. This system samples load current at a pivotal moment in the cycle, ensuring that if a non-zero condition is detected when it should be zero, a relay will activate to engage a circuit breaker or perform other necessary functions. The second patent involves a controller designed for SCRs that leverages digital control of the phase angle of the firing signal, specifically during rapidly changing power frequencies. This digital control utilizes clocking signals derived from generator rotation, providing a consistent number of pulses per electrical cycle, regardless of frequency changes.
Career Highlights
Throughout his career, Lilienthal has worked with notable companies including Research Incorporated and Control Concepts, Inc. His career is marked by a commitment to advancing SCR technology, ensuring that innovations not only improve functionality but also enhance safety in electronic applications.
