Switch - ON Semiconductor
www.onsemi.comEssentially, the semiconductor power switch creates an AC voltage from the input DC voltage. This AC voltage can then be stepped−up or down by transformers and then finally filtered back to DC at its output. Switching power supplies are much more efficient, ranging from 65 …
Power Semiconductor Switching Devices
www.egr.unlv.edu• Power semiconductor devices first appeared in 1952 with the introduction of the power diode. • The thyristor appeared in 1957. Thyristors are able to withstand very high reverse breakdown voltage and are also capable of carrying high current. One disadvantage of the thyristor is that once it is in the
