Abstract:
A control circuit for controlling an electrical load having a load input, said control circuit comprising:(a) a power input for receiving an input AC waveform having a selected RMS value,(b) a rectifying circuit coupled to said input for producing at a power output one of a plurality of output waveforms from said AC input waveform, each output waveform having an RMS value substantially the same as said selected RMS value,(c) a controller coupled to said rectifying circuit and operative to cause said rectifying circuit to produce at said power output a selected one of said output waveforms,(d) said load input being adapted to be coupled to said power output for receiving said selected output waveform so that said selected output waveform provides power to said load,(e) and a decoder control circuit adapted to be coupled to said power output and to said load and responsive to the selected output waveform from said rectifying circuit for controlling said load.
