New five-level active neutral point clamped converter
2013 IEEE Energy Conversion Congress and Exposition, 2013Multilevel converters are a proven solution for medium voltage and high power applications including renewable energy conversion. Developing 6.6 kV converters is a key goal for the wind turbines industry. Considering the voltage rating of commercially available semiconductors, five-level converters are necessary to reach 6.6 kV.

1 kW PFC converter with compound active-clamping
IEEE 34th Annual Conference on Power Electronics Specialist, 2003. PESC '03., 2004A PFC converter employing compound active clamping technique is proposed. It can effectively reduce the loss caused by diode reverse recovery. Both the main switch and the auxiliary switch can achieve soft-switching (ZVS) under certain conditions. The parasitic oscillation caused by the parasitic capacitance of the boost diode is eliminated.

Effect of clamp capacitor on the stability of active-clamp DC-DC converters
PESC 98 Record. 29th Annual IEEE Power Electronics Specialists Conference (Cat. No.98CH36196), 2002This paper discusses the effect of an active-clamp circuit on the dynamic characteristics of a basic converter topology such as a buck-boost power converter. The buck-boost converter has instability problems such as a jumping phenomenon and an oscillation of the output voltage. Recently, the authors have found an unstable phenomenon due to inserting an
