Optimal topologies of resonant dc/dc converters
Abstract
Generalized and optimal topologies of zero-voltage-switching and zero-current-switching resonant DC/DC power converters are presented. It is shown that many equivalent topologies of the converters can be derived from each of the generalized topologies. The generalized topologies of the converters show clearly which of the parasitic capacitances and inductances can be absorbed into the LC resonant circuit. Utilizing this fact, optimal topologies that are the most suitable for high-frequency operation are derived. In the optimal topologies, the greatest possible number of parasitic reactances is included harmlessly in the resonant circuit. Optimum layout and component selection guidelines for the converters are given. High-order resonant converters are also developed.
