I want to measure the voltage across the IGBT to moniter the voltage if there is short circuit or not and then feed it back to microcontroller? what is the best way of doing that. Do i have to use a differential amplifier, isolation amplifier or voltage transducer. i am attaching the circuit. if you have any circuit to measure the voltage please try to post. the maximum voltage when the device is on is equal to Vce (sat) is 1.8V according to the data sheet. the maximum voltage when device is off 120V.
