Title: Rohan Dayal: Innovator in Power Electronics

Introduction

Rohan Dayal is a notable inventor based in Madison, Alabama, recognized for his contributions to the field of power electronics. With a total of three patents to his name, he has made significant advancements in driver circuits and surge protection technologies.

Latest Patents

One of Rohan's latest patents is a surge protection circuit for a half-bridge power converter. This innovative driver circuit provides power from a power source to a load and includes essential components such as a surge protector, an input stage, a controller, an overvoltage protection circuit, and an output stage. The input stage efficiently receives power from the source and establishes a direct current (DC) power rail. The controller manages the output stage to deliver power from the DC power rail to the load. Importantly, the overvoltage protection circuit ensures the controller shuts down when the DC power rail exceeds a predetermined voltage, thereby protecting the output stage from potential damage.

Another significant patent is the constant current source LED driver circuit with a self-clamped output. This driver circuit supplies current to a light source from a resonant tank featuring a single inductive element. The circuit is connected to a DC power source and includes a power inverter that provides AC input to the tank. The design incorporates a DC blocking capacitor and a primary winding of the inductive element, which is arranged in series between the inverter's output and the ground. The leakage inductance of the inductive element serves as resonant inductance for the tank, distributing power output to multiple secondary windings connected to an output rectifier.
