      H-Bridge, 3-Phase motor, MOSFETs, Pulse With Modulation (PWM) ... The Current continues to the winding in phase U then goes through the phase V winding. From there current goes through the MOSFET in phase V on the low side. Then the timing from the microcontroller will make the current flow through the different phases at different times indicated in Figure3. Caution the timing must be correct ...
