The field of switching electronics poses challenging control problems that cannot be treated in a complete manner using traditional modeling and controller design approaches. Class D amplifiers invite the application of advanced hybrid systems methodologies. Nowadays, the recent theoretical advances in field of hybrid systems is inviting both the control and the electronics communities to revisit the model and the control issues. Motivated by this, a novel model for Class D is outlined in this paper. As motor drives and dc-dc conversion fields, the hybrid control theory can be applied to audio amplifier but the first step is to find the good hybrid model to describe the system.
