I am designing MPPT charge controller. I have chosen my mosfets to be both nmos https://www.sparkfun.com/products/10213 (FQP30N06L) 60V, 30A. Since the gate voltage is 3 to 5V. I can drive the low side from an arduino, however, how can drive the high side ? since Vg should be higher than Vs, which in this case is Dvin (around 37 V). A lot of people say using a half bridge driver. But also there is a problem. The output voltage is present always (battery voltage), which causes a problem for the driver.
