Some Topologies of High Quality Rectifiers
نویسنده
چکیده
Several basic classes of three-phase high-quality rectifiers are described. Both single-switch and six-switch three-phase rectifier topologies can be derived from parent dc-dc converters. Single-switch rectifiers are compared with the basic six-switch PWM rectifiers performing similar power conversion functions, using the measures of total semiconductor stress and active semiconductor utilization. The single-switch approach is shown to utilize the semiconductor devices more effectively. Zero current switching and multiresonant approaches are found to exhibit low switch stress over a wide range of operating points, with low THD.
