Power Diode: Symbol, Construction, Working, Types and Applications

A power diode is a semiconductor device specifically engineered to conduct large currents and withstand high reverse voltages in power electronic circuits. It is fundamentally a PN junction diode, but its internal structure, doping profile, and packaging are optimized for high-power operation rather than low-level signal processing. In power electronic systems, power diodes play a […]
