:The output of 3-level PWM are in-phase with each other which yields three distinct voltage levels of voltage differential over the load. The third voltage level is ''zero voltage'' which features lower current rate of change in the coil yielding lower total current ripple. | :The output of 3-level PWM are in-phase with each other which yields three distinct voltage levels of voltage differential over the load.
