Title: Majid Naveed and His Patent for Reducing Capacitive Coupling Effects

Introduction

Majid Naveed is an inventor associated with Mohegan Lake, New York, and Philips Electronics North America Corporation. His patent work addresses a control problem in switched-mode power supplies, where parasitic capacitance can disrupt reliable operation.

Latest Patents

Naveed is credited with 1 patent: “Arrangement for Reducing the Effects of Capacitive Coupling in a Control.”

The invention concerns switched-mode power supplies in which a controller and switching device are encapsulated together with a heat sink. Because the switching device’s drain is connected to the heat sink, parasitic capacitances can form between the heat sink and paths leading to the controller’s pins. Switching can then cause unwanted currents to flow into or out of those pins. In particular, a resulting voltage drop at the V_CTRL pin may interfere with control circuitry and push the power supply out of regulation.

The patent describes a track-and-hold circuit connected between the V_CTRL pin and the control circuitry. It mirrors the voltage across the discharge capacitor and isolates the circuitry from the temporary undervoltage caused by capacitive coupling.

Career Highlights

Naveed’s documented patent contribution focuses on improving control stability in switched-mode power supplies. The approach addresses unwanted electrical effects within the device arrangement and helps protect the control signal during switching.
