Suppose you are planning to go on a country-side tour riding your bike. In an unfortunate situation, you find the bike battery drained and currently you don’t have access to any spare battery or workshop. The only power source you have access to is the AC supply of 120V (rms) at 50 Hz. You check the battery and it’s clear from the description level that the battery requires 12V DC source to charge up. Moreover, you are well aware that the socket mounted to your available AC source gives spike that’s sometimes provide higher value than the rated one. To solve this problem, you plan to build a diode-based circuit to obtain a continuous and fixed voltage output as well as solve the instability problem of the source. Criteria: 1. Consider regular diodes, Zener diodes, resistor, and capacitor as your available components. However, the only available diodes here are Ge based and Si based. 2. You must choose a diode with PIV rating higher than the peak value of AC input. 3. Your designed system must be able to prevent the voltage spikes from hampering your battery. 4. You should test both type of diodes to reach an optimum setting regarding the best possible circuit arrangement. Based on this criterion, prepare the following: i. Identify and analyze the circuit with the help of diode application theories and examine the operations of the identified circuit with appropriate connections and adequate ratings of components and sources to satisfy all criteria ii. Compare your designed circuit with different type of diodes to reach the best outcome based on their characteristics and behavior in a circuit Don't reject the question please.
Suppose you are planning to go on a country-side tour riding your bike. In an unfortunate situation, you find the
bike battery drained and currently you don’t have access to any spare battery or workshop. The only power source
you have access to is the AC supply of 120V (rms) at 50 Hz. You check the battery and it’s clear from the
description level that the battery requires 12V DC source to charge up. Moreover, you
are well aware that the socket mounted to your available AC source gives spike that’s sometimes provide higher
value than the rated one.
To solve this problem, you plan to build a diode-based circuit to obtain a continuous and fixed voltage output as
well as solve the instability problem of the source.
Criteria:
1. Consider regular diodes, Zener diodes, resistor, and capacitor as your available components. However,
the only available diodes here are Ge based and Si based.
2. You must choose a diode with PIV rating higher than the peak value of AC input.
3. Your designed system must be able to prevent the voltage spikes from hampering your battery.
4. You should test both type of diodes to reach an optimum setting regarding the best possible circuit
arrangement.
Based on this criterion, prepare the following:
i. Identify and analyze the circuit with the help of diode application theories and examine the
operations of the identified circuit with appropriate connections and adequate ratings of components
and sources to satisfy all criteria
ii. Compare your designed circuit with different type of diodes to reach the best outcome based on
their characteristics and behavior in a circuit
