Abstract :
This paper presents the design of a 14 kW three-phase 400/480 Vac input telecom rectifier module with 56 Vdc/250 Adc output current. A three level input rectification stage with sinusoidal input current is discussed in detail. All the control functionality is implemented by using a digital signal processor (DSP). The design of the digital controller is carried out entirely in z-domain. Simulation results and measurements with prototypes demonstrate the validity of the theoretical results.
