Sliding mode multilevel control for improved performances in powerconditioning systems

A novel control technique has been devised to obtain high dynamics responses from a multilevel power conditioning converter. The theory of variable structure control systems with sliding mode has been followed, taking into account several problems that may be encountered in space environments. The analytical study made provides general tools to design AC power conditioning systems for any application. The new control scheme, its mathematical analysis and digital simulation results relevant to a 115 V/400 Hz AC power system are presented and discussed
