Abstract
A power converter is capable to convert an electrical input power into a bipolar output power and to deliver the bipolar output power to at least two independent plasma processing chambers. The power converter includes a power input port for connection to an electrical power delivering grid, at least two power output ports each for connection to one of the plasma processing chambers, and a controller configured to control the power converter to deliver the bipolar output power to the power output ports, using at least one of control parameters including power, voltage, current, excitation frequency, and threshold for protective measures. The controller includes a virtual power supply for each power output port, and each virtual power supply includes a separate complete set of all fixed and time varying parameters and internal states associated with the operation of the individual power output port.
