Abstract
Power signals having controllable peak-to-peak amplitudes are provided to electrode sets so that during a first period of time, a first amplitude signal is provided to a first electrode set and a second amplitude signal is provided to a second electrode set. The first amplitude is greater than the second amplitude and bipolar current flows from the first electrode set to the second electrode set. During a second period of time, a third amplitude signal is provided to the first electrode set and a fourth amplitude signal is provided to the second electrode set. The third amplitude is less than the fourth amplitude and the current flows from the second electrode set to the first electrode set. Alternating first and second periods of time establish repetitive bipolar current flow between electrode sets. The addition of a backplate establishes unipolar current flow.
