This is essential in systems that use distributed power rails (like 24 V to 48 V), which must be locally converted to 15 V, 12 V or 5 V with very little power loss. The buck converter uses a transistor as a switch that alternately connects and disconnects the input voltage to an inductor (see Figure 5). WebSince the total loss of % Ì Ç » H 8 Â Ç is generated at the resistor in each cycle of switching, a loss of % Ì Ç » H 8 Â Ç H B Ì Ð is generated. The loss is generated in the snubber circuit even without any load, as long as the switching operation is being performed, resulting in lower efficiency. Figure 1.
