PWM Amplifier Control Loops With Minimum Aliasing Distortion by yamnat.temp is a document available to read on EtoBox.
This convention paper discusses the modeling of PWM class-D audio power amplifiers, focusing on the control loop filter and the effects of aliasing distortion. It presents a large-signal model that accounts for non-linear sampling effects and derives closed-form expressions for total harmonic distortion in traditional loop configurations. The paper introduces Minimum Aliasing Error (MAE) loop filters and validates the model through simulations and practical measurements.
