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 ...

Infineon Technologies has introduced a single power module that can handle up to 352kW in three-level solar string inverter applications. Called F3L600R10W4S7F_C22, and aimed at for 1.5kVdc inverters, ...

Scientists in India have tested a new inverter topology with a single-phase, induction-motor water pump. The seven-level inverter, with five power semiconductor switches, is said to be particularly ...

Researchers in Iraq have designed a multi-level cascaded inverter that can purportedly produce high-quality sinusoidal output voltage and current waveforms, while reduing harmonic distortion. It uses ...

Earlier this week, Californian company Pre-Switch claimed 99.3% efficiency for a 100kHz electric vehicle traction inverter running at 100kW. It credits this impressive figure to the use of a resonant ...
