Abstract :
This paper describes the practical realization of an electronic smoothing inductor (ESI) topology, which can reduce the harmonic current level, the output voltage ripple, and the volume of diode bridge rectifiers with a low realization effort. The control strategy and an EMI filtering concept for the ESI are presented and are verified by numerical simulation and experimental results for steady state and dynamic operation. By using the ESI a power density of 7.9 kW/dm3 for a 5 kW rectifier prototype is realized. Furthermore a high efficiency of 98.6% and an improved power factor of 0.956 is obtained.
