Characteristics and applications of fast recovery epitaxial diodes
Read about epitaxial ultrafast diodes in thia app note from IXYS. (PDF)
During the last 10 years, power supply topology has undergone a basic change. Power supplies of all kinds are now constructed so that heavy and bulky 50/60 Hz mains transformers are no longer necessary. These transformers represented the major part of volume and weight of a traditional power supply.
