Theoretical estimation of distorting effects by trr of parasitic MOSFET-Diode in DCI-NPC audio power amplifiers
IEICE Electronics Express
One of the topologies that can work at high Power and high Quality simultaneously is the DCI-NPC topology. This new topology has new parts and presents new voltage and distortion errors. One of these new elements are the MOSFET parasitic Diodes. These Parasitic-Diodes presents a Recovery Reverse Time (t rr ) and its distorting effects generates signal and quality losses, and EMI problems. These phenomena are introduced, modeled, studied and evaluated to discuss the affectation importance of thedoi:10.1587/elex.9.484 fatcat:h6d3yttsnjcobas5pmj7oq7z7u
