Abstract :
A comparison of power circuit topologies and fluorescent lamp current control strategies for medium to high power rapid-start high-frequency ballasts is presented. Issues such as output current harmonic content, current crest factor, and starting current are addressed. It is found that the LCC type and the LCLC type power converter satisfy the lamp requirements. The LCLC type converter has the added advantage of having the lowest kVA rating. Experimental results for the LCC type power converter under voltage mode control are provided
