Abstract :
In this paper a sliding mode approach is proposed to analyze and design two different switching schemes: the pulse ratio modulator and the hysteresis current regulator. The problem of the possible presence in the voltage modulator of a low bandwidth transducer, is overcome by means of a suitable feedback compensation. A current regulator scheme which needs the knowledge of only the fundamental current harmonic is also presented and compared with the usual hysteresis one. Several simulation results show the effectiveness of the proposed scheme
