Abstract
Bias supplies, plasma processing systems, and associated methods are disclosed. One bias supply comprises a first inductor coupled between a first node of a switch and an output node where a first node of a second inductor is coupled to one of the output node or the first node of the switch. A voltage source is coupled between a second node of the switch and a second node of the second inductor. A connection is made between the return node and one of the second node of the switch and the second node of the second inductor. The bias supply also comprises a controller configured to cause an application of the periodic voltage between the output node and the return node by repeatedly closing the switch so current through the switch completes a full cycle.
