It retains the preferred output voltage by dispersing the overload of power in a "pass" power transistor, but the SMPS quickly switches a power transistor between saturation and cutoff with a changeable duty sequence whose average is the preferred output voltage, resulting in better efficiency.
is generally known, today announced the development of a Gallium Nitride (GaN) power transistor with the ultra high breakdown voltage over 10000V.
Tokyo, Japan, Oct 18, 2005 - (JCNN) - Oki Electric Industry announced on October 17 that it has developed a power transistor with dramatically improved amplifying characteristics, in collaboration with the Research Center for Micro-Structure Devices at the Nagoya Institute of Technology.
