中文摘要：
适应高频链能量变换的特点,提出一种新型双Boost高频逆变电路,该拓扑由两个全控开关和两个储能电感构成,通过占空比大于0.5的控制方法实现高频升压及逆变输出。相对普通的全桥高频逆变电路,该拓扑可减少开关个数以提高变换效率,缩小高频变压器变比进而减小其体积和分布参数,因此可广泛应用于具有高频逆变要求的电路中。在分析其结构特点及工作原理的基础上,提出一种以双Boost高频逆变电路与典型三相输出型高频链矩阵变换器相结合的新拓扑,详细分析了Boost电感电流连续模式（CCM）下该电路高频开关周期内的工作状态,给出了相应的仿真和实验波形,结果证实了该拓扑在高频链能量变换器中应用的可行性及其控制方案的合理性。
英文摘要：
According to the characteristics of high-frequency linked energy conversion,a new type of topology-double Boost high-frequency inverter circuit is proposed.The new topology consists of two fully-controlled switches and two storage inductors,and can achieve boost in any switching cycles by duty ratio greater than 0.5 control method.Compared to full-bridge high frequency inverter circuit,it can reduce the inverter circuit switches,and the high-frequency transformer turns ratio,it also can reduces the size of the transformer and distribution parameters.The topology can be widely used in many high-frequency conversion circuits as the invert circuit.Based on the description of the structural features and work prinples of the new circuit,a new type of high frequency linked inverter is proposed based on the combination of dual-Boost invert and matrix conveter,and the various working conditions in one high frequecy AC cycle are analyzed,and the relevant simulation and experimental waveforms are also shown.The results prove that the application of the new topology and its control strategy of energy change in the high-frequency link converter are feasibility.
