Title: The Innovative Contributions of David Doss
Introduction
David Doss is a notable inventor based in Overland Park, Kansas. He has made significant contributions to the field of electrical engineering, particularly in the development of power supply circuits for gas discharge tubes. With a total of 5 patents to his name, Doss has demonstrated a commitment to innovation and technological advancement.
Latest Patents
One of Doss's latest patents is a power supply circuit designed for high voltage, low current gas discharge tubes, including neon, argon, and mercury vapor. This invention utilizes a free-running, flyback oscillator that converts D.C. voltage energy into radio frequency energy through a compact ferrite transformer and associated circuitry. The primary winding is tuned by a resonant capacitor and is driven by a power transistor. A high voltage, center-tapped winding of the ferrite transformer directly drives the gas tube load. The design includes a feedback winding across the transistor base and emitter junction, which sustains oscillation and regulates the drive level of the transistor. The oscillator can be started using an on-off switch that supplies a single starting pulse or a time-delayed starting pulse. Additionally, a MOSFET transistor connected to the power transistor base, along with a current sensing transformer in series with the primary winding, momentarily disables the power transistor at the end of a conducting cycle. This innovative design allows the transistor to withstand a forward voltage of 700 volts in the off state.
