Title: Alagan Thiruvarul Selvakkumaran Sathyan: Innovator in Power Supply Systems

Introduction

Alagan Thiruvarul Selvakkumaran Sathyan is a notable inventor based in Tamil Nadu, India. He has made significant contributions to the field of power supply systems, holding a total of four patents. His innovative work focuses on enhancing the efficiency and functionality of power supply circuits.

Latest Patents

One of his latest patents is titled "System and method for input power detection of two power sources using single monitoring circuit." This invention describes a voltage supply system that includes a first power supply branch and a second power supply branch. Both branches feature a voltage supply, a serially connected diode, and a switch connected between the voltage supply and the output of the voltage supply system. Additionally, a gate driver is connected to the first switch to control its operation. The system also incorporates a voltage monitor/controller designed to perform a built-in test by managing the state of the first and second switches through enable signals provided to the gate drivers.

Another significant patent is "Zener diode power path control for extended operation range of linear power supplies." This power supply system consists of a direct current (DC) power source and a protection circuit with input and output. The input is operably coupled to the DC power source, allowing it to receive DC power during operation. The protection circuit includes two paths that electrically couple the input to the output, with current primarily passing through the first path when the input voltage exceeds a threshold related to a Zener diode in the second path. Conversely, current flows primarily through the second path when the input voltage is below the threshold. The system also features a voltage regulator connected to the output of the protection circuit.
