Activity 1: A rectifier circuit is used to charge a 12 Vdc battery using a 40 Vp-p AC source, according to the following circuit. ibatt 2002 ww RECTIFIER 12 Vdc 40 Vp-p (AC) (1-a) Build a half-wave rectifier circuit with a single diode to perform the charging function. Explain the operation of the diode and the entire circuit. Use drawings to illustrate how battery current changes with the input voltage. (Assume that diodes turn on at 0 V) (1-b) Build a full-wave rectifier circuit with four diodes to perform the charging function. Explain the operation of the diodes and the entire circuit. Use drawings to illustrate how battery current changes with the input voltage. (Assume that diodes turn on at 0 V) (1-c) Assuming practical diodes in the full-wave rectifier, describe the behaviour of a single diode as a p-n junction, then analyse the operation of the entire rectifier assuming 0.7-V threshold voltage for each diode. Use simulations to support your analysis.
The circuit shown below is to be used to provide a stabilised output to the load. The Zener diode characteristic is also shown on the next page. Find the load voltage (VL) and source current (IS) if the battery voltage is 18 V, series resistance is 1.4 KΩ and load resistance is 11 KΩ. Additionally, determine the value of the source resistance (R) if the Zener diode is at the threshold of activating in its reverse bias. Comment on the purpose of having this value of R in the circuit.
2. For the circuit shown below, find the current in and voltage V1. Assume the forward bias voltage of the diode is 0.7V. The easiest way to think about this problem is to consider what the circuit does BEFORE the diode is added, i.e., compute V1 without the diode, then add the diode to see if it alters the circuit behavior. 5 V ww 3 ΚΩ V1 ww 2 ΚΩ 5 V +
