The results show that the phase error of the vector measurement is zero, and amplitude errors can be eliminated, and high measurement accuracy can be obtained by using low bit D/A converter.
Stable output voltage and input power factor is available by direct adjustment of the amplitude and phase angles of the control voltage for 4qs converter.
