An AC-to-DC power conversion by connecting GTO elements to the positive arms of a three-phase full wave bridge circuit and by repeating the mode of supplying power to a load from an AC power supply by controlling the GTO elements, and the mode of making the current flowing to the load ...
The fixed switching frequency control for a single-phase boost AC to DC converter to achieve a sinusoidal line current and unity power factor is proposed i... TC Chen,TJ Ren,JC Ou - 《Energy Conversion & Management》 被引量: 12发表: 2009年 Redundant Operation of a Parallel AC to DC Con...
DC to AC converters for cars are devices that allow a car to run on AC power. They are used to convert the DC power that is provided by the car’s battery into AC power that can be used to operate the car’s electrical components. How does a AC to DC converter work? Fig.1 A ...
A high frequency AC/DC converter with unity power factor and minimum harmonic distortion A novel forced commutated AC/DC converter and control strategy is proposed that is able to draw nearly sinusoidal currents at unity power factor from three... Wernekinck,E.,Kawamura,... - 《Power Electronic...
This paper presents a power converter and its control circuit for high-frequency-fed ac to dc conversion. Based on the resonant technique, the input current is shaped to be sinusoidal and is forced to follow the high-frequency sinusoidal input voltage so as to achieve unity power factor. With...
