DC Solid State Relay Using Mosfet & Optically Isolated Gate Driver With Current Feedback & Fault Output

Leave a comment

DC solid state Relay build using optically isolated Mosfet gate driver & high current Mosfet, this relay also provides current feedback as voltage output and fault TTL voltage output when  current goes above set point.  Current feedback designed around op-amp  as signal conditioning  which measure the current across low ohm shunt resistor.  On board preset (trimmer pot) to adjust the

DC Solid State Relay Using MOSFET & Optically Isolated Gate Driver

Leave a comment

This project has been designed around TLP250/352 which is Opto-Coupler IGBT/MOSFET Gate Driver from Toshiba and Mosfet IRFP260 from IR, This relay consists of optically isolated gate driver and low impedance Mosfet. The combination of low resistance and high load current handling capabilities make this Relay suitable for a variety of switching applications.  These devices are ideally suited for controlling
