摘要
船舶运行环境复杂多变引起电磁耦合频率大幅提升,随之带来的集肤与邻近效应,使得漏感计算无法反映真实谐振回路中电流的变化情况,导致漏感校正效果不佳。因此,提出船舶电力电子变压器漏感自动校正方法。通过在船舶电力电子变压器电路中设置感应装定磁场耦合系统,检测初级线圈谐振回路中电流的变化情况,以此确定是否产生漏感。在产生漏感时,以微型逆变器控制模块为基础,基于单边校正网络设计双边校正网络。通过双边校正网络调整初级侧和次级侧的校正电容值,实现船舶电力电子变压器漏感自动校正。实验结果显示所提方法应用后的输出电流在30 s内达到稳定状态,电压幅值成功回升到2 V左右的正常水平,有助于确保船舶电力电子变压器稳定。
The complex and variable operating environment of ships causes a significant increase in electromagnetic coupling frequency,resulting in skin and proximity effects that make leakage inductance calculations unable to reflect the actual changes in current in the resonant circuit,leading to poor leakage inductance correction results.Therefore,an automatic correction method for leakage inductance of ship power electronic transformers is proposed.By setting up an induction device magnetic field coupling system in the ship's power electronic transformer circuit,the changes in current in the primary coil resonant circuit are detected to determine whether leakage inductance is generated.When generating leakage inductance,a bilateral correction network is designed based on a single-sided correction network using a micro inverter control module as the basis.By adjusting the correction capacitance values of the primary and secondary sides through a bilateral correction network,automatic correction of leakage inductance in ship power electronic transformers can be achieved.The experimental results show that the output current of the proposed method reaches a stable state within 30 s after application,and the voltage amplitude successfully recovers to a normal level of around 2 V,which helps to ensure the stability of ship power electronic transformers.
