摘要: 随着有源相控阵雷达的发展，相控阵雷达对发送接收（TR）电源的需求不断提高，宽输入电压范围、高频化和高效率的TR电源成为当今的主流研究方向。双有源桥（DAB）变换器能够实现宽输入电压范围，并且控制方式多样化，在TR电源领域具有广泛的应用前景，但DAB变换器的电感量和开关频率等系统参数对TR电源的传输功率和功率MOS管的通态电流影响很大。基于DAB变换器中的扩展移相（EPS）调制方法，推导了其功率传输特性和电感电流大小等表达式，并以考虑过载需求的最大传输功率、MOS器件最大通态电流降额设计、最小输出电压纹波频率为限制指标，提出一种基于EPS调制下的DAB电路参数优化设计方法，基于参数限制规划了可靠运行区ROA，为设计相应的电感值、开关频率，优化DAB参数提供参考依据。最后通过对两路输出的DAB变换器进行相应的MATLAB仿真分析，仿真结果表明输出电压纹波、MOS管通态电流大小、输出功率符合预期需求指标，验证上述理论推导的准确性。Abstract: With the advancement of active phased array radar, the requirement for transmit-receive (TR) power supplies in phased array radar has been escalating continuously. TR power supplies featuring wide input voltage range, high frequency, and high efficiency have emerged as the prevailing research orientation nowadays. Dual active bridge (DAB) converters can realize wide input voltage range and offer diversified control methods, thereby holding extensive application prospects in the domain of TR power supplies. Nevertheless, the system parameters such as inductance and switching frequency of DAB converters exert a considerable influence on the transmission power of TR power supplies and the on-state current of power MOSFETs. Based on the extend-phase-shift (EPS) modulation approach in DAB converters, this paper deduces the expressions of power transmission characteristics and inductor current magnitude, and proposes a parameter optimization design method for DAB circuits under EPS modulation. With the maximum transmission power considering overload requirements, the derating design of the maximum on-state current of MOS devices, and the minimum output voltage ripple frequency as restrictive indicators, the reliable operation area (ROA) is planned based on the parameter limitations, providing a reference basis for designing the corresponding inductance value, switching frequency, and optimizing DAB parameters. Finally, through the corresponding MATLAB simulation analysis of a two-output DAB converter, the simulation results indicate that the output voltage ripple, the on-state current of MOSFETs, and the output power conform to the expected demand indicators, validating the accuracy of the above theoretical derivation.
