Abstract :
The paper presents new small-signal modeling of uniformly-sampled three-phase PWM modulators. The models reveal that the uniformly-sampled modulators, which are commonly used in three-phase power conversion, introduce delays and additional coupling between the power converter control inputs, as well as time-variation of the power converters´ small-signal dynamics. Experimental results are given
