Abstract:
An RF amplifier system having improved power supply, comprising:a plurality of power amplifiers each having an output circuit for connecting a DC voltage source across one of a plurality of primary windings located on a first transformer; a controller that controls said amplifiers; said first transformer having a plurality of secondary windings located thereon with said secondary windings each being a single turn secondary winding, said secondary windings being connected together in series such that an output voltage is developed across said secondary windings of a value dependent upon the operation of said amplifiers; a second transformer located in a cascaded arrangement with said first transformer and having a like plurality of single turn primary windings connected together in series, said single turn primary windings on said second transformer being connected in parallel with the said single turn secondary windings on said first transformer; a like plurality of secondary windings are on said second transformer with each being connected to a rectifier for providing a controlled DC voltage.
