Title: Scott G Leslie: Innovator in Power Electronics
Introduction
Scott G Leslie is a notable inventor based in Pittsburgh, PA (US). He has made significant contributions to the field of power electronics, holding 2 patents that showcase his innovative approach to technology.
Latest Patents
One of his latest patents is for a Variable Gain Switch. This invention involves a power bipolar transistor that incorporates a MOSFET within the base region. The MOSFET is designed to short the transistor's emitter and base regions together when the bipolar transistor is in an off condition with a large base to collector voltage. Additionally, the bipolar transistor features floating guard rings, with the gate of the MOSFET connected to one of these rings. This design allows the MOSFET gate to receive a voltage when the depletion region from the base to collector junction reaches the floating guard ring, effectively turning on the MOSFET and providing the emitter to base short.
Another significant patent by Leslie is a Triggering Method for Light Triggered Thyristors. This invention outlines a method for triggering a light triggered thyristor (LT²) using a light source to provide background excitation of carriers in the amplifying gate areas of the LT² prior to triggering. The background excitation is kept at a low level to avoid triggering the device or causing excessive leakage current. At the desired moment, a second light signal is employed to trigger the LT².
