Introduction

Ronald D Hreha is an accomplished inventor based in Asheville, NC (US). He has made significant contributions to the field of power semiconductor devices, showcasing his expertise through his innovative patent.

Latest Patents

Hreha holds a patent for a "Short-circuit protection for a power semiconductor device." This invention involves a desaturation detector that receives signals from a gate driver and circuitry, indicating whether a power semiconductor device is on and in desaturation. A logic circuit processes these signals, leading to an output from a latch circuit. The output signal has two distinct values: one for the as-designed condition and another for a short-circuit condition. When the power semiconductor device transitions to a short-circuit state, the output signal changes, prompting the gate driver to switch off the device. Additionally, filters are incorporated to reduce noise within the desaturation detector. Hreha's innovative approach enhances the reliability and safety of power semiconductor devices.
