Study and evaluation of MOSFET Rds(ON)-impedance efficiency losses in high power multilevel DCI-NPC amplifiers

This work justifies the usefulness of multilevel Powe Amplifiers with DCI-NPC (Diode Clamped Inverter–Neutral Point Converter) topology in applications where size and weight needs was optimized. These Amplifiers can work at high frequencies thereby reduces the size and weight of the filter elements....

Zusammenfassung:	This work justifies the usefulness of multilevel Powe Amplifiers with DCI-NPC (Diode Clamped Inverter–Neutral Point Converter) topology in applications where size and weight needs was optimized. These Amplifiers can work at high frequencies thereby reduces the size and weight of the filter elements. However, it is necessary to study, analyze and evaluate the efficiency losses because this amplifier has double number of switching elements. This paper models the behavior of the MOSFET Rds(ON) in a DCI-NPC topology for different conditions. Peer Reviewed
