采用复合控制的SPWM逆变电源研究
Research on SPWM Inverter Adopted Compound Control
摘要
Abstract
According to the characteristics of the low voltage DC power supply of the inverter,on the basis of the main control strategy for inverter and unipolar&weak frequency multiplication SPWM,a compound control method for the inverter was proposed,the method of the compound control was introduced including voltage RMS loop control, DC component control,repetitive control,voltage and current double close-loop instantaneous value control,etc.With the DSC MC56F8346 as the core,a 4 kV·A inverter prototype using the low voltage DC power supply was designed,the detailed hardware and software implementation method were given,and a experimental verification was done,and the results show the feasibility of SPWM inverter design using this compound control mode.关键词
