| 摘 要： | 为降低大功率变换器产生的谐波,提出了一种基于LCL结构的直接双并联变换器的拓扑结构及其控制方式。采用交错采样调制技术可以提高变换器的等效输出开关频率,利用基于虚拟电阻的改进型控制策略能有效抑制谐振。仿真和实验结果证明了该策略的有效性。 |

| Abstract: | A new topology of direct dual parallel converter based on LCL structure and its control strategy are proposed.To reduce the harmonic of high power converters,staggered sample technology is applied.For the sake of suppressing the reso-nance,the improved control strategy based on virtual resistor is proposed.The simulation and experimental results prove the effectiveness of this strategy. |
| Keywords: | converter parallel virtual resistance staggered sample |
