This document provides a step-by-step example of calculating component values for a buck converter circuit that converts 12V to 5V at 2A. It calculates the required inductor value, output capacitor value, input capacitor value, diode selection, MOSFET selection, and efficiency. It then examines how to modify the design to a synchronous buck converter using an additional MOSFET for rectification to improve efficiency.

Part A: Comparators and Switching (5%)
(1) Signal limit detector
Use a 339 comparator, a single 74LS02 quad NOR gate and a +5V power supply only to
design a circuit which will detect when a voltage goes outside the range +2.5V to +3.5V
and such that an LED lights and stays lit. Provide a manual reset to extinguish the LED.
Design hints
1. The circuit has an analog input and a digital output so some form of comparator circuit
is required. There are two thresholds so two comparators are required, with the analog
input applied to both. This arrangement is sometimes known as a window detector.
2. Arrange the output of the comparators to be +5V logic levels, and combine the two
outputs logically to produce one signal which is for example, high for out-of-range, and
low for within-range.
3. Latch the change from in-range to out-of-range.
Design procedure
1. Start at the output and work backwards.
2. Select a latch circuit (flip-flop) and determine what combinations of inputs are needed to
latch and then reset it, ensuring that the LED is connected correctly with regard to both
logic and current flow.
3. Determine the logic needed to combine two comparator outputs in such a way as to
correctly operate the latch.
4. Choose comparator outputs which will correctly drive the logic. Remember that the
reference voltage at the input of the comparator may be at either the + or – input.
5. Choose resistors to provide the correct reference voltages.
Note: You will need to consult data for both the 74LS02 and the 339 (see data sheets).
Test
It is strongly recommended that you assemble and test your circuit.
(2) MOSFET Switching
Find out information on the operation of, and configuring of, MOSFETs to be used in
switching circuits. In particular note the differences between BJTs and MOSFETs in this
role. Draw up a table to highlight the differences and hence the pros and cons on each
device for particular situations (eg. Switching high-to-low or low-to-high (ie. P or N type),
high or low current switching, low or high voltage switching).
Consider the following BJT switching circuit. Analyse the operation of the circuit to
understand the parameters involved. Choose suitable replacement MOSFETs to be used

instead of the output switching BJTs in the given circuit. Include any necessary circuit
changes for the new devices to operate so as to maintain the circuit’s required parameters.
Where Vcc = 12V and Relay resistance = 15Ω .

Bypass Capacitor is a capacitor that shorts AC signals to the ground. This article explains the types of bypass capacitors, functions, and its applications
The conventional lighting sources like incandescent and fluorescent lamps are replaced by High Brightness Light Emitting Diodes (HB-LEDs). In this paper, a HBLED driver using a Single Ended Primary Inductor Converter (SEPIC) with input Power Factor Correction (PFC) is presented. PFC is accomplished using a commercial inexpensive Peak Current Mode Controller (PCMC) IC UC3842 is newly combined with SEPIC converter. Extensive simulation results are carried out and a laboratory prototype to power 18W LED array from AC mains is implemented and the results are presented in detail.

Securing your Kubernetes cluster_ a step-by-step guide to success !KatiaHIMEUR1
Today, after several years of existence, an extremely active community and an ultra-dynamic ecosystem, Kubernetes has established itself as the de facto standard in container orchestration. Thanks to a wide range of managed services, it has never been so easy to set up a ready-to-use Kubernetes cluster.
However, this ease of use means that the subject of security in Kubernetes is often left for later, or even neglected. This exposes companies to significant risks.
In this talk, I'll show you step-by-step how to secure your Kubernetes cluster for greater peace of mind and reliability.

Epistemic Interaction - tuning interfaces to provide information for AI supportAlan Dix
Paper presented at SYNERGY workshop at AVI 2024, Genoa, Italy. 3rd June 2024
https://alandix.com/academic/papers/synergy2024-epistemic/
As machine learning integrates deeper into human-computer interactions, the concept of epistemic interaction emerges, aiming to refine these interactions to enhance system adaptability. This approach encourages minor, intentional adjustments in user behaviour to enrich the data available for system learning. This paper introduces epistemic interaction within the context of human-system communication, illustrating how deliberate interaction design can improve system understanding and adaptation. Through concrete examples, we demonstrate the potential of epistemic interaction to significantly advance human-computer interaction by leveraging intuitive human communication strategies to inform system design and functionality, offering a novel pathway for enriching user-system engagements.

Elevating Tactical DDD Patterns Through Object CalisthenicsDorra BARTAGUIZ
After immersing yourself in the blue book and its red counterpart, attending DDD-focused conferences, and applying tactical patterns, you're left with a crucial question: How do I ensure my design is effective? Tactical patterns within Domain-Driven Design (DDD) serve as guiding principles for creating clear and manageable domain models. However, achieving success with these patterns requires additional guidance. Interestingly, we've observed that a set of constraints initially designed for training purposes remarkably aligns with effective pattern implementation, offering a more ‘mechanical’ approach. Let's explore together how Object Calisthenics can elevate the design of your tactical DDD patterns, offering concrete help for those venturing into DDD for the first time!
