Summary:This paper comprehensively analyzes the relationship between
space-vector modulation and three-phase carrier-based pulse width
modulation (PWM). The relationships involved, such as the relationship
between modulation signals (including zero-sequence component and
fundamental components) and space vectors, the relationship between the
modulation signals and the space-vector sectors, the relationship
between the switching pattern of space-vector modulation and the type of
carrier, and the relationship between the distribution of zero vectors
and different zero-sequence signal are systematically established. All
the relationships provide a bidirectional bridge for the transformation
between carrier-based PWM modulators and space-vector modulation
modulators. It is shown that all the drawn conclusions are independent
of the load type. Furthermore, the implementations of both space-vector
modulation and carrier-based PWM in a closed-loop feedback converter are
discussed
