THD of Closed-Loop Analog PWM Class-D Amplifiers

open access: yesIEEE Transactions on Circuits and Systems I: Regular Papers, 2008
This paper presents an analytical modeling of the mechanisms of total harmonic distortion (THD) of second-order based single-feedback and double-feedback Class-D amplifiers (CDAs).

THD Analysis of a Modulation Technique Applied for THD Reduction

2013 Brazilian Power Electronics Conference, 2013
This work presents the THD analysis of the modulation technique previously described in [1]. The proposed technique showed an improvement in the power quality, reducing the total harmonic distortion in flying capacitor multilevel inverters, combining the advantages of two modulation techniques: HE-PWM and CSV-PWM.

An Analysis of THD in Class D Amplifiers

APCCAS 2006 - 2006 IEEE Asia Pacific Conference on Circuits and Systems, 2006
The paper investigates the parameters affecting THD and PSRR in a PWM class D amplifiers with feedback. From our mathematical analysis, the authors show that the THD and PSRR of a PWM class D Amplifiers with feedback can be improved by shaping the frequency response of the 2nd-order integrator.
