    PCB design and schematic for a half bridge power amplifier

    Hi, I am making a half bridge power amplifier that operates at 24 V. The bridge has to supply around 3A current to an inductive load (10mH) The bridge will be controlled using 20kHz PWM from a microcontroller. I have put a ACS712 current sensor in the load path to give feedaback to the...
