Vehicle Body Metal Detector Circuit

Last Updated on November 27, 2023 by Swagatam 2 Comments

block diagram

The main objective we are trying to achieve with this vehicle body metal detector is that only an automobile can trigger the opening of the gate. The solution involving the interruption of a light beam is not suitable, so we turned to a metal detector, as metal is a primary material in any automobile. In […]

Using MOSFET Body Diodes to Charge Battery in Inverters

Last Updated on January 2, 2021 by Swagatam 116 Comments

full bridge battery charger circuit

In this post I have explained how the internal body diodes of MOSFETs could be exploited for enabling the charging of battery through the same transformer which is being used as the inverter transformer. In this article we will investigate a full bridge inverter concept and learn how the in-built diodes of its 4 MOSFETs […]
