Patent ID: 8009452

Claim:
A power supply, comprising: a power source having at least one power source output; and a plurality of drivers connected to said at least one power source output, at least one of said plurality of drivers comprising: a bridge network comprising a first switch, a second switch and a bridge network output, said first switch connected between said at least one power source output and said bridge network output, said second switch connected between said bridge network output and a voltage reference node, said bridge network further comprising at least one control input connected to said second switch, wherein said bridge network is adapted to change a state of the first switch based on a state of the second switch, said at least one power source output of the power source comprising an envelope waveform output, said at least one of said plurality of drivers being an envelope-driven driver wherein a waveform at said bridge network output tracks a waveform at said envelope waveform output.
