A novel switching power loss estimation method for modular multilevel converters (MMCs) with the nearest level modulation (NLM) is introduced in this paper. It focuses on the switching actions caused only by change of the inserted submodule (SM) number per arm, named as the essential switching transitions. Every essential switching action can be identified under the assumption of ideal sinusoidal...
Pseudo-differential circuits approximate the performance of fully-differential structures, while allowing single-ended operation of the two half stages in the circuit. This requires duplication of the circuitry, with accurate symmetry needed between the two halves to cancel common-mode noise. This paper proposes a single-ended scheme which uses double sampling and time interleaving to achieve a performance...
