Title: Edwin J Wroblewski: Innovator in Electric Load Control
Introduction
Edwin J Wroblewski is a notable inventor based in Milwaukee, WI (US). He has made significant contributions to the field of electric load control, holding 2 patents that showcase his innovative approach to technology.
Latest Patents
One of his latest patents is the Modular Electric Load Controller. This invention features a modular construction with logic circuitry housed in an enclosure. The circuitry includes a microprocessor, I/O interface, and memory for storing the computer program executed by the microprocessor. The control logic sends signals through the I/O interface to three modules that switch three-phase electric current to the load. Each switch module contains thyristors that apply electricity to the load in response to control logic signals. These modules are mounted on a heat sink, with the logic circuit enclosure positioned on top. Additionally, a protection circuit module may be included, featuring a metal oxide varistor and a capacitor connected across each phase of the electric power.
Another significant patent is the Cartridge for Magnetically Operated Contacts. This invention describes a pushbutton switch where a pair of contact cartridges containing magnetically operated sealed switches are mounted to an actuator section. The linear motion of the pushbutton is converted to rotary motion by a cam structure in each cartridge. A magnet, positioned between two switches, rotates about a switch axis. By polarizing the magnet and using a magnetic shield, the switches operate as the magnet rotates, allowing for multiple modes of operation.
