Abstract : A time sequence of square waves is summed to provide minimum distortion high power voltage sinusoids. The phase difference of two identical sinusoids is varied to control the resultant summed amplitude. Amplitude modulation of the sum sinusoid is achieved through varying the phase relationship between the two identical sinusoids. Frequency and phase modulation is achieved through digital control of the individual square waves. (Patents)
