TL;DR: In this article, the effects of key sources of total harmonic distortion (THD) in power output signals of digitally controlled switchmode (Class-D) converters/amplifiers are analyzed.

TL;DR: In this article, a balancing converter concept with ZVS is introduced and the operation of a string of PV panels equipped with balancing converters is analytically described, based on this analytic framework, different examples of shading scenarios of a PV string are examined regarding the average inductor current values that occur within the balancing modules, in order to derive the required specifications of a balanced converter.

TL;DR: In this paper, the delta connection of three single-phase boost unity power factor rectifier units ( ∆-rectifier) is analyzed based on an equivalent star connection, and the stresses on the power components are calculated in analytical form in order to provide a basis for a comprehensive comparative evaluation.

TL;DR: An approach for shaping the stator geometry of a permanent-magnet (PM) synchronous machine, such that an arbitrary CT pattern can be obtained by an iterative algorithm, which adds sinusoidal air gap modulation components on an initial machine geometry.

TL;DR: In this paper, a Pareto curve in the η-THD space is drawn which highlights the relationship between the nonlinear behavior of the output capacitance of power MOSFETs and input current distortions.
