Below attached my design for buck MPPT
All of the port will connect to pin header and to the microcontroller board. I wish to test this buck converter board individually without connecting to the MCU board. So, the buck is supplied with 18V from DC power supply in order to step down to 12V battery charging voltage. I am giving PWM signal to IR2104 driver at pin 2 using signal generator. However I fail to turn on my NMOS because there is no output at IR2104. After sometime the R7 of 100 Ohm resistor at current sense burned. Is there any problem with the current sense circuit ?
1. Is my way of testing correct?
2. Is my design for buck converter works for MPPT application ?
Thank you
