Title: Eric W. Suomi: Innovating Low Voltage Overcurrent Protection Systems
Introduction:
Eric W. Suomi is an accomplished inventor based in Madison, WI. He holds a notable record of seven patents, reflecting his dedication to advancing technology, particularly in the realm of overcurrent protection in solid-state switching systems. His inventions have made significant contributions to the field, demonstrating a blend of creativity and technical prowess.
Latest Patents:
Among Eric's latest patents is a system designed for low voltage overcurrent protection for solid-state switching. This innovation involves a current sensing transformer with a low impedance primary winding connected in series with a filter and load circuit. The output current is supplied by a high-frequency PWM power supply, like a sine wave dimmer. The invention includes a microprocessor-based programmable controller that executes a routine involving a variety of overcurrent tests. It handles different output current values over varying time durations, enabling specific tests solely at low output voltages or dimming levels. When any test is satisfied, the power switching stage of the power supply is deactivated to halt operation.
Another of his significant patents focuses on overcurrent protection within solid-state switching systems. This involves current sensing resistors attached directly to output terminals of MOSFETs that construct the series switching stage of a PWM sine wave dimmer. An EMI resistant current link transmits an analog current signal to comparators that indicate overcurrent conditions. Through a logic circuit, PWM control signals from a programmable controller can be overridden, allowing for the series switching stage to cease conduction, while a clamp switching stage is activated until the end of the current PWM duty cycle power-on segment. The logic circuit effectively communicates an overcurrent signal via an optocoupler to the controller, which monitors for overcurrent signals at a clock frequency. If the counts exceed predetermined limits within specific cycles, it ensures the safety of the system by rendering the appropriate stages nonconductive.
