ROBUST-CONTROL OF SWITCHED POWER CONVERTERS VIA SLIDING MODE

This paper presents a variable structure control approach for the outp ut voltage regulation of switched power converters. The most outstandi ng feature of this control technique is its robustness towards load an d line voltage disturbances. A control implementation for a basic down converter based on state-space transformation wholly confirms this pe rformance. An extension to inverter control results in reduced harmoni c distortion in case of uncertain load characteristics. Analytical pre dictions are verified by experimental results.
