A compact transformer coupled modulator is described. The modulator includes a transformer comprising a primary and a plurality of secondary windings, where each secondary winding has an output terminal. The modulator also includes a plurality of switches, where each switch is associated with a respective secondary winding and has input and output terminals and a control terminal. The control terminal of each switch is in electrical communication with a respective output terminal of the plurality of secondary windings. Each of the plurality of switches is substantially simultaneously switched by an input signal applied to the primary.

High power modulator

A method of coating an article wherein the method includes placing a large number N of non-industrial stock pieces in a vacuum chamber where N is a function of the cost of each stock piece, generating a plasma about the stock pieces, and supplying a current to the stock pieces at a level tailored to sufficiently coat each of the plurality of stock pieces with ion from the plasma and wherein the current level depends on the number N of stock pieces.
