Abstract - AC-AC converter offers much better energy
efficiency than conventlonal two-stage power converters or
Inverters. Thls poper reports a new modular phase bank design
approach of AC-AC Converters that sipnificm~tlyre ducer the s h e
and weight of the power converter and Improves the power
density. The modular approach and Integrated AC power
modules offer a much Improved deslgn for the power drcults at
affordable cont. In the paper, a preliminary theoretical analysis
of the sfllcon utilizetion and the AC switch ratings for thb new
breed of power converter Is presented. A DSP based low-at
system control Is dlscussod. Potentld maJor Industry rppllceHons
are also evaluated and highlighted In this paper. Experimental
results verify the design.
