Control loop design of parallel connected converters using sliding mode and linear control techniques

This paper shows the design of a parallel connected converter system using both linear control techniques applied to small-signal models and sliding mode control. The paper presents a sliding mode strategy as an alternative design method. This different approach allows to endow the system with prominent dynamic characteristics. Analysis and design consideration are investigated in the case of sliding mode control.
