External TVS diodes can be used to supplement the internal clamping diodes of ICs. Surge ability of silicon TVS diodes are related to size. External TVS diodes can be 10x larger than internal clamping ...

In the conventional design of a forward converter, the maximum duty cycle can be extended above 50% by using a reset and clamp technique. This technique, known as RCD clamp circuitry, consists of a ...

In October, we described how to snub the voltage across output rectifiers at turn-on in the forward converter. Now, we look at snubbing the FET turn-off voltage in the flyback converter. Figure 1 ...

Often used in dc-dc converter modules for power levels below 100 W, single-transistor, resonant reset forward converters are also useful for dc-dc converters with adjustable output voltages. Among ...
