The prototype inverter is implemented with discrete components; a picture of the inverter and controls is shown in Fig. 6. It cansynthesize ac waveforms into its rated load from 0～300V over the frequency range 200kHz to 2MHz. The six-phase waveforms are accurate to within 1.5% in magnitude and 4° of phase over the operating range. The largest harmoniccomponent is at least 19.8 dB (a factor of 9.8)
