Abstract
A pulsed power system and a pulsed power sputtering system are disclosed. The pulsed power system includes a first power source that is configured to apply a first voltage at a first power lead that alternates between positive and negative relative to a second power lead during each of multiple cycles. A second power source is coupled to a third power lead and the second power lead, and the second power source is configured to apply a second voltage to the third power lead that alternates between positive and negative relative to the second power lead during each of the multiple cycles. A controller is configured to control the first power source and the second power source to phase-synchronize the first voltage with the second voltage, so both, the first voltage and the second voltage, are simultaneously negative during a portion of each cycle and simultaneously positive relative to the second power lead during another portion of each cycle.
