Soft-Switching DC-AC Converters

Soft-switching techniques are developed to reduce switching losses, cun·ent and voltage stresses and EMT. Under asoft-switching condition, switching frequency can be increased and thereby the size and volume of the conve1ter canbe reduced. This paper is an attempt to classify the soft-switching dc-ac topologies in a simple and generic way. Theresonant topologies employing soft-switching are classified based on the location of resonant network in the inverterwhith respect to load, de-link and ac-link_Some possible industrial applications of soft-switched dc-ac converters areaddressed.
