    Abstract: Resonant tank parameters critically influence both steady state and dynamic performance of LLC resonant converters. However, conventional design methodologies often overlook dynamic behavior during the design stage. To address this limitation, this paper proposes a co-design methodology for LLC converters that simultaneously considers steady state and dynamic performance. Based on an accurate dynamic time domain model, the influence of resonant tank parameters on both steady state and small signal characteristics is comprehensively analyzed. To enable a fair quantitative assessment of dynamic performance, the worst-case operating condition for compensator design is identified, and the maximum achievable loop gain crossover frequency under this condition is adopted as the performance metric. A hierarchical design procedure is then developed, in which the feasible design space is progressively narrowed by steady state constraints and dynamic performance requirement. Within the reduced design space, a multi objective optimization is performed to obtain the Pareto-optimal trade-off between root-mean-square (RMS) current and loop gain crossover frequency. The proposed method is verified on a 1 kW prototype. Compared with a steady-state-oriented conventional design, the proposed approach achieves more than double the crossover frequency, reduces voltage overshoot/sag by 15%-46%, and shortens the settling time by 20%-56%, with a 0.50% peak efficiency sacrifice.
