| 摘 要： | 高电能质量的直-交变换器在生产和研究领域越来越受到人们的重视.Buck-Boost直-交变换器具有较低的谐波分量,可以消除传统控制理论中的动态调整过程.变换器由两个完全相同的Buck-Boost直-直变换器反串联组成.两个变换器给定电压的幅值相同、相角相差180o,迭加后在输出端得到正弦电压.采用能量控制的方法,使每次从输入端传递到输出端的能量等于给定所要求的正弦波能量与负载所需能量的代数和.仿真结果证明了基于能量传递控制的Buck-Boost直-交变换器控制策略的正确性.

| Abstract: | Higt power quality DC-AC converters have atlracted much more att ention to both production domain and research domain.And the DC-AC converter proposed by this paper has low total harmonic distorion(THD),and it can also eliminate the dynamic regulation process which emerges in traditional control method.This converter is composed of two same Buck-Boost DC-DC converters. Driving both Buck-Boost converters' sinusoidal references with the same magnitude and 180~o phase-shifted,the differential output voltage is therefore an ac output voltage.The method of energy control makes the energy whicn transfers from imput to output equals to the algebra sum of energy requested in sinusoidal references and that needed in load.And the simulation result shows the validity of energy transfer controled Buck-Boost DC-AC converter. |
