Abstract

See full text

This disclosure describes systems, methods, and apparatus for reducing ripple in a pulsed waveform power generation system, often for use providing power to a plasma processing chamber. A snubber can be provided between a DC power supply and a switching circuit. A buck converter can also be provided between the snubber and the switching circuit, where the buck converter takes its input from within the snubber and in particular from between a rectifying and capacitive component of the snubber. In this way, the buck converter can be isolated from the DC power supply via an input inductor on a high-input line from the DC power supply.
