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.

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 ...

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 is designed to integrate IGBT technology with lower switching and conduction losses ...

The Technologie-Lizenz-Büro (TLB) is offering licenses for manufacturers in the field of wind power, motor control, electricity supply systems and uninterruptible power supplies. On 5 September 2013, ...

Unidrive SP includes an encoder-equipped ac induction motor that accurately controls speed and position for a wide range of loads. G7 ac drive features 480-V 3-level inverter architecture to eliminate ...

The U.S. conglomerate plans to deploy and test new controls with its commercial PV LV5 inverter platform. It aims to develop “grid-forming” controls to allow wind and solar inverters to form voltage ...

Scientists in India have developed a 500 W seven-level inverter prototype based on switched capacitors. The device is reportedly able to achieve a high efficiency despite switching, conduction, and ...
