| 摘 要： | 针对高磁场磁共振大孔径人体成像系统中超导磁体电源在励磁时向磁体充能、退磁时把能量“逆变”回电网的设计要求，比较了两种能量回馈型的拓扑结构。通过 Matlab 仿真分析，验证了拟采用的拓扑结构的合理性。

| Abstract: | The power supply of high field magnetic resonance superconducting magnet in a large aperture human body imaging system works in two aspects,i.e.normal excitation and demagnetization.The demagnetization energy is returned to the power grid through the"inversion"of the power supply.According to the design requirements,two kinds of energy feedback topologies are analyzed and compared.The proposed topology is analyzed and simulated with the Matlab/Simulink analysis. |
