Introduction

John Phillip Schmitz is a notable inventor based in Oakdale, MN (US). He has made significant contributions to the field of power conversion technology. With a total of two patents to his name, Schmitz has developed innovative solutions that enhance the efficiency and functionality of power converters.

Latest Patents

One of Schmitz's latest patents is the "Synchronous Rectifier Gate Drive Shutdown Circuit." This invention involves a power converter that includes a transformer, a bridge input circuit, a self-driven synchronous rectifier circuit, a gate drive circuit, and a gate drive shutdown circuit. The transformer features a primary winding connected to the bridge input circuit, along with a first and a second secondary winding. The self-driven synchronous rectifier circuit is linked to the first secondary winding and includes a first synchronous rectifier that rectifies voltage across the first secondary winding. The control terminal of the first synchronous rectifier responds to voltage across the second secondary winding. The gate drive circuit incorporates a first diode connected to the control terminal of the first synchronous rectifier, introducing a DC level shift. The gate drive shutdown circuit is connected to the first diode and includes a switch that removes the DC level shift from the control terminal when the operation of the bridge input circuit is terminated.

Another significant patent is the "Active Snubber Circuit for Synchronous Rectifier." This snubber circuit is designed for use with a self-driven synchronous rectifier in a power converter. It captures and recirculates energy from the leakage inductance of the converter in a substantially lossless manner. The snubber circuit comprises a capacitance that stores energy accumulated in the leakage inductance of a transformer winding. Additionally, it includes a discontinuous inductor and a switch that transfers the stored energy to the inductor when activated. The energy in the inductor can then be discharged when the switch is off.
