Three-phase four-switch inverters represent a cost‐effective and efficient alternative to conventional inverter topologies, offering reduced component counts while maintaining robust performance.

Scientists in the Emirates have conceived a new space vector pulse width modulation method that reportedly reduces switching losses and increase efficiency in three-phase photovoltaic inverters. The ...

Today’s VFDs rely on fast-switching IGBTs that can generate steep dv/dt levels, voltage reflections across long motor cables, ...

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 ...

EPC has introduced an evaluation board implementing a 40Arms (60A peak) three-phase inverter that will run from 30V to 130V. Called EPC91200, it is “suitable for 80 and 110V battery systems commonly ...

Silicon carbide (SiC) power devices have been commercially available for ten years. During that time, there has been a steady increase in voltage ratings to 1,200 V and 1,700 V for SiC-Schottky diodes ...

With the increasing popularity of alternate power sources, such as solar and wind, the need for static inverters to convert dc energy stored in batteries to conventional ac form has increased ...
