Power source for plasma device
A plasma device including a power source for creating an AC output signal with a matrix transformer between said power source and a series circuit comprising a first lead and a second lead. The matrix transformer including at least two modules with a first primary portion formed of first and second tubes connected at one end and a second primary portion formed of third and fourth tubes connected at one end, with said third and fourth tubes mounted in, and electrically isolated from, said first and second tubes, respectively, where said concentric tubes define generally parallel elongated passages through the module. A secondary winding is wrapped through the elongated passages of each module. There is a first series circuit from the power source to the matrix transformer for passing the first polarity of the AC output signal through the first primary sections of the modules, a second series circuit from the power source to the matrix transformer for passing the second polarity of the output signal through the second primary sections, a rectifier for each of the secondary windings of the modules and a third series circuit connecting the rectifiers in series with the first and second leads so a voltage of over about 500 volts is across these leads.
