Experimental Results for the Single Capacitor Single Inductor Active Snubber

In this work the practical results obtained with the Single Capacitor Single Inductor Active Snubber (SCSIAS) circuit using the Diode Bridge Switch Configuration are presented, proving the advantages of this proposed topology, which can be implemented with minimum component count. The SCSIAS configuration ensures that the main power devices undergo a ZVS off-commutation and a ZCS on-commutation, minimizing commutation losses in all operating conditions. Snubber topology also ensures that most auxiliary commutations take place under zero voltage/zero current conditions.
