Abstract |
In recent years, the importance of resonant converter topologies to the power conversion industry has
increased significantly, with the requirement for increasingly smaller power supplies for more
compact electronic equipment, and higher efficiency supplies for increased battery life and/or to meet
environmental constraints. Furthermore, the improved performance characteristics that can be
obtained by employing high-order tank circuits have attracted interest in complex resonant power
circuitry. However, hand-in-hand with the increased complexity of such high-order resonant
converters, comes the increased difficulty in modelling of their performance at the design stage. This
is predominantly due to the fact that appropriate converter topologies exhibit several degrees of
freedom, and also tend to have long settling times compared to the switching period. This paper aims
to contrast and compare a number of techniques that have been proposed to address these, and other
pertinent issues. |
