Hi,
i am building a small scale inverter. contol part is done through a microcontroller and transformer is driven by a Power mosfet. As the microcontroller power source is 5V and power mosfet needed around 7V min as Vgs, i used an optocoupler with another power source of 12 V. I have attached the circuit too. However it does not seem like the power mosfet switches on correctly according to the input pulse. Am i doing anything wrong here?
