Computer-aided Accurate Modeling and Design Optimization for Isolated Resonant DC-DC Converters
Abstract
Traditionally, the fundamental harmonic analysis (FHA) method is utilized to analyze and model resonant converters. However, massive harmonics exist when a wide voltage gain range operation is required. To address this issue, based on accurate time-domain model and with the aid of computer mathematical software (like MATLAB), both steady-state and dynamic circuit waveforms of these power converters can be accurately derived. In addition, small signal model is very challenging but important for resonant converters. Conventionally, the extended describe function is adopted to derive the small signal model, where only the fundamental harmonics are considered, which leads to low accuracy and unoptimized design. With the aid of resonant converters accurate dynamic circuit models, the small signal models for resonant converters under various operation modes can be simply derived and used to guide the controller design and stability analysis.
Conventional power converter design is mostly based on engineering experience and simplified FHA circuit model. In addition, the commercial simulation software is involved and massive simulations have been executed to find out the final design candidate. Clearly, conventional power converter design method is both inaccurate and time-consuming. With the aid of accurate time-domain circuit model and advanced optimization algorithms, comprehensive and optimal design methods for these advanced resonant DC-DC converters are discussed.
