Power Diode

A power diode is a two terminal, anode a and cathode K and  two layer P  and  N  junction devices. A PN  junction normally  formed  by allowing  diffusion and epitaxial growth  structure of a power diode. Basic structure and symbol of power of a power  diode have larger  power voltage and diode are shown  in figure 1.1  power  diodes  have larger power  voltage  and current  handling  capabilities  than ordinary signal diodes. In  additions  the  switching  frequencies of power  diodes are low  as compared to signal  diodes. Some  applications  of these  devices are electric traction, battery charging  electro plating  electro metal processing power supplies  welding  Ups  etc.
