Abstract :
This paper presents an experimental switched-reluctance generator (SRG) based distributed power system with common DC grid and single-phase AC 220/110V 60Hz outputs. First, a SRG with suitably designed power converter and control scheme is constructed to generate robust DC 48V output. Then it is boosted to establish a 400V common DC grid by a current-fed push-pull (CFPP) DC/DC converter. Well-regulated output with galvanic isolation is obtained by the developed converter. Finally, a typical load-side single-phase three-wire (1P3W) transformerless 220V/110V inverter is developed. A master and a slave robust control schemes are proposed to yield good and balanced sinusoidal output voltage waveforms under varied system load conditions.
