Power converter topologies with reduced component count for automotive AC auxiliary power

A impressive series of new products has emerged in response to the increasing number of entertainment and workshop systems powered up from the vehicle´s low voltage battery. As most of these products feature the same typical power architecture, new solutions with reduced component count are looked for. They are expected to reduce cost, reduce loss, and improve reliability. This paper makes a brief review of the topic and discusses new topologies. Results are included for a 100W converter.
