ABSTRACT:
A multi-phase power system including a plurality of Pulse Width Modulation (PWM) controllers is provided, including a first PWM controller and at least one second PWM controller. The first PWM controller is configured to generate at least one first output signal based on a first clock signal, and to insert at least one synchronizing pulse into the first clock signal, the synchronizing pulse having a predetermined characteristic differing from pulses of the first clock signal, and to provide the first clock signal including the synchronizing pulse to the second PWM controller. The second PWM controller is configured to generate at least one second output signal based on the first clock signal, and to synchronize the generation of the first and second output signals using the synchronizing pulse within the first clock signal, thereby maintaining a predetermined phase relationship between the first and second output signals. The synchronizing pulse may be, for example, a skinny pulse or a pulse having a magnitude larger than the pulses of the first clock signal.
