| Abstract |
In this paper a practical investigation of a VIENNA Rectifier III is presented. The stresses on the
power components are calculated in analytical form based on the analysis of an equivalent DC/DC
converter system. This gives the basis for the dimensioning and practical realization of a 8.5kW
400VAC/48VDC prototype of the system. There, for system control an outer output voltage control loop
and an inner output inductor current control loop are provided and implemented on a digital signal
processor (ADSP 21061) which transfers the relative on-times of the power transistors to an EPLD for
generation of the gating signals of the power transistors. Finally, the dependency of the efficiency, of
the power factor and of the THD of the mains current on the output power as gained from
measurements on the prototype are given. |
