Abstract :
This paper presents a quantitative analysis of the operating characteristics of three-phase bridge rectifiers with AC-side reactance and constant-voltage loads. We describe the operating characteristics of the three-phase diode bridge rectifier in continuous conduction mode. Simple approximate expressions are derived for the output current characteristic, as well as the input power factor. The output current control characteristic is also derived for the three-phase thyristor bridge converter with constant-voltage load. The derived analytical expressions are applied to a practical example and simulations are utilized to validate the analytical results
