摘要：
In this paper is proposed the implementation of a novel structure for a Class D amplifier based on a robust closed loop control. The proposed control it is based on a multi level sliding mode controller. This allows of being able to converge to a stable status in spite of unknown or nonlinear elements present in the amplifier. The methods and systems proposed are also described. Several simulation results are presented. The obtained results confirm the potential of this configuration, as it is shown in the last part of this paper.
