A new class of hybrid AC/AC direct power converters [PDF]

open access: yes, 2005
Variable voltage and variable frequency conversion of electrical energy from an AC source to an AC load is done in traditional power converters via a DC-link where an energy storage element (electrolytic capacitors) is situated.
