|Title:||Performance improvement of soft-switched PWM rectifiers with inductive load|
|Abstract:||A new soft-switched ac/dc pulse width modulation (PWM) converter structure is presented, It is useful for current-fed inverters and PWM rectifiers, Typical applications are magnet power supplies, high-power ac motor drives, and active power filters with magnetic energy storage, Soft switching is provided at the expense of a limited increase of the circuit complexity as compared to usual hard-switching solutions, A discussion of the soft commutation process is presented, By a proper switching sequence, overvoltages across the converter switches can fully be eliminated, Moreover, light-load operation can be achieved, Both typical limitations of soft-switched current-fed topologies are therefore overcome. Simulation and experimental results demonstrate the actual converter capabilities.|
