When we speak of efficiency, we are referring mainly to electrical efficiency. This usage, however, is a restriction of the meaning of the word efficiency itself. In power-electronics applications the ...

Although they require more complex circuits, three-level inverters are more efficient than their two-level cousins. Effective partitioning simplifies implementation of the three-level configuration.

Three-level rectifiers and inverters constitute a critical component in modern power conversion systems, offering improved voltage quality, reduced harmonic distortion and increased power efficiency ...

Semikron has added a new topology for use in three-level inverters to its Semitop IGBT product range. The topology integrates IGBT technology with lower switching and conduction losses to produce ...
