摘　　要：研究了基于DSP控制的串并联谐振变流器,提出了基于励磁电感Lm和品质因数Q的谐振腔参数设计方法,并在TMS320F28335芯片中实现了全数字化控制。最后制作了一台实验样机,实验结果表明,应用此设计方法所设计出来的变流器具有较高的变换效率,从而验证了所提出的谐振腔参数设计方法的准确性和数字控制实现方法的可行性。Series and parallel resonant converter based on DSP was studied, design methodology of resonant tank based on magnetizing inductance L,, and Q factor was proposed, and full digital control was realized using TMS320F28335 chip. Finally, a prototype was build, and experimental result demonstrated the high power conversion efficiency applying the presented design method. Hence, the accuracy of the proposed design method of resonant tank was verified, together with the feasibility of the digital realization method.
