Title: Innovations of James Michael Walden

Introduction

James Michael Walden is a prominent inventor based in Apex, NC (US). He has made significant contributions to the field of electrical engineering, holding a total of 10 patents. His work primarily focuses on advanced power management systems and control circuits.

Latest Patents

One of his latest patents is the "Flyback converter with secondary side regulation." This invention includes flyback converters, control circuits, and methods to facilitate secondary side regulation of the output voltage. A primary side control circuit operates a primary side switch to independently initiate power transfer cycles to deliver power to a transformer secondary winding in a first mode. Additionally, a secondary side control circuit operates a synchronous rectifier or secondary side switch to generate a predetermined cycle start request signal via a transformer auxiliary winding to assume secondary side regulation and to cause the primary side controller to initiate new power transfer cycles.

Another notable patent is the "Slew-rate compensated transistor turnoff system." In this system, a transistor control circuit is configured to adjust a control voltage at a transistor control output responsive to a comparison signal at a control input. The control voltage has a slew rate. A comparator has a comparator output and first and second comparator inputs. The first comparator input is coupled to the transistor control output. The comparator is designed to provide the comparison signal at the comparator output based on a reference voltage at the second comparator input. It also deactivates the transistor control circuit by changing the state of the comparison signal responsive to the control voltage falling below the reference voltage. A slew-rate compensator is configured to increase the reference voltage by a compensation voltage that compensates for a time delay of the comparator or the transistor control circuit. The compensation voltage is proportional to the slew rate.
