| Research Abstract |
The purpose of this research is to develop a new intelligent general-purpose switching power supply system by introducing a digital control scheme to the system. To achieve this purpose, a control method with single design parameter which able to control multi-channel and multi-level voltage output system is proposed. Here, by introducing an adaptive function, it is experimentally verified that control performance degradation caused by the nonlinearity behavior in the system such as from input voltage perturbation, load variation, AD/DA resolution error and switching regulation could adaptively be compensated. Moreover, realization method of low cost, robust and appropriately considered AD/DA resolution controller for limit-cycle variation of output voltage that is caused by digitization is proposed.
