Power Semiconductor Devices
Diode is a 2-terminal PN junction semiconductor device with terminal anode (A) and Cathode (K).
P-N junction is formed by alloying, diffusion and epitaxial growth.
Current Rating: 1 A -Several thousand A
Voltage Rating: 15 V -50 kV
When anode is made at higher potential than the cathode , the device is said to be forward biased and a forward current starts to flow from A to K.
Switching Characteristics of Diode:
Various categories of Power Electronics Converter
Different types of PE converter are presented below:
