(iv) [2 Marks] A pn-junction has a built-in potential voltage of 1V across the junction. The width of the depletion region is 1um. The acceptor doping is NA 2 x 1015cm-3 in the P-side and a donor doping is Np = 8 x 1015cm-3 on the N-side. If the reference position x 0 is the edge of the depletion region on the P-side and the P region is on the left of the N region then where does the maximum...

Ctri Question 3 (20 Marks) Lab 1-Zener Circuits and Applications Theory: Zener diode is designed to operate in reverse conduction. Zener breakdown occurs at a precisely defined voltage, allowing the diode to be used as a voltage reference or clipper. While Zener diodes are usually operated in reverse conduction, they may also be operated in cutoff and forward conduction. There are two different effects that are used in "Zener diodes". The only practical difference is that the two types have...
DC-AC inverters have many commercial and residential applications, including uninterruptible power supply (UPS) units, adjustable speed drives (ASD) for AC motors, and electronic frequency changer circuits. They are also used in solar electrical systems where batteries are charged from solar panels and used as the input DC voltage source. The inverter circuit converts the DC into AC voltage of desired frequency. Most of us are also familiar with HVDC transmission systems, where high voltages are first converted from AC to...
