Abstract: Three-phase bi-directional ac-dc converters are required to have high efficiency. To improve efficiency, it is required to decrease the number of switching transition. Therefore, a novel ...

Abstract: To address the issue of low efficiency under light load conditions when CLLLC converters employ fixed-frequency pulse width modulation, this paper proposes a fixed-frequency improved pulse ...

Doing more with less in electronics often means improving power density. One of the new areas garnering attention involves applying a variety of advanced modulation techniques, including PWM and space ...

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 ...

Pulse Width Modulation or PWM technology is used in Inverters to give a steady output voltage of 230 or 110 V AC irrespective of the load. The Inverters based on the PWM technology are more superior ...
