Abstract

This paper deals with the effects of input supply voltage unbalance on the steady-state, small-signal dynamic and transient performance of AC/DC buck rectifiers with modulation magnitude and phase angle control. Operations with balanced and unbalanced input supply voltage source are compared. A comprehensive analysis based on the complex d-q-n synchronous reference frame transformation and harmonic balance technique shows that third harmonic input current and second harmonic output voltage components are generated as additional components due to imbalance voltage source
