Title: Arthur O Fitzner: Innovator in Voltage Regulation and RFI Suppression

Introduction

Arthur O Fitzner is a notable inventor based in Fond du Lac, WI (US), recognized for his contributions to the field of electrical engineering. He holds a total of 17 patents, showcasing his innovative spirit and technical expertise. Fitzner's work primarily focuses on voltage regulation and methods to protect engine electronics from radio frequency interference (RFI).

Latest Patents

Fitzner's latest patents include a voltage regulator designed for internal combustion engines equipped with permanent magnet alternators. This innovative voltage regulator utilizes an SCR/diode bridge rectifier and incorporates crowbar SCR overvoltage protection. The design ensures that the crowbar SCR has sufficient time to cool off after being triggered by an overvoltage surge. The system detects crowbar SCR operation to generate a control signal that activates a timer, effectively shutting off gate drive to the main bridge SCRs. This mechanism allows for adequate recovery time for the crowbar SCR, preventing damage from excessive heat.

Another significant patent involves a system and method for protecting engine electronics from RFI effects. This invention includes inserting high-frequency shunts in the wires connected to an electronic control module housed in a metal enclosure. The shunts, which consist of bypassing capacitors, are strategically placed to ground the incoming wires and the active circuit of the module. This design minimizes RFI interference, ensuring the reliable operation of electronic components.
