Abstract
An approach to power circuit estimation on the base of simple energybased heuristics was derived by analysing the mathematical principles of resonant power systems intuitively. Practical illustration of the use of this approach is demonstrated for power electronics application design especially of classE and halfbridge topologies. Experiments indicate that optimisation with intelligent restrictions allows to avoid huge computational expense, and provide prediction of areas with both, high parameter sensitivity, and low parameter sensitivity. The energybased heuristic approach was proved by logical consistence of topological construction principles, as well as by a remarkable number of loadresonant topologies confirming the theory. To confirm this method to be mathematically applicable, the exact calculation of the used energybased operators of the heuristic method provided improved agreement between exact system solutions at ideal ZVS/ZCS conditions of the conside red power converters, and their solutions of the approach within parameterinsensitive operation areas. The provided solution understands optimization first of all as a sensitivity analysis to identify the robust areas of system operation in terms of parameter deviation influence before operating areas are set.
