As a first step, we consider a biobjective optimization problem where the first objective evaluates stability of circuit operation and the second objective evaluates ripple in current sharing. Using a piecewise constant modeling, the two objectives and the Pareto front are calculated: the existence of a trade-off between the two objectives is guaranteed exactly, no approximation. In numerical experiment, typical waveforms on the Preto front are conffermed.}, title = {並列化昇圧コンバータの効率と安定性のトレードオフ}, year = {2024} }
