Reference Design of Battery Charger With MPPT

Solar energy harvesting is on the rise, but the main drawback of solar energy harvesting is that it can only generate electricity when the sun is present in the sky. To...

Multibay charger for 2S configuration

Do you want to charge a 2S battery pack, or want a charger that can be customised to charge up to 32 cells? Then the reference design from MPS is suitable...

Understanding Hydroponics

Life seems to find its ways in highly irrelevant nonliving spaces. Little did the barbaric clans of World War II ever imagine that a 180 steps descent old, suffocating, deserted tunnel...

Aligning Capacitor Selection With The Latest Automotive Demands

Capacitors are common passive elements in all electronic devices, including vehicles. The usage of capacitors in vehicles is expected to increase in the coming years as electric vehicles (EVs) gain popularity....
STRAIN GAGES FOR MEASURING STRAIN AND STRESS ON A PCB

Strain Gages For Measuring Strain and Stress On A PCB

The main objective of PCB tests is to determine the principal strains in the areas of high strain concentration, especially at the corners of large circuit components. With PCB strain gauge tests,...

Analogue Front Ends For Heart Rate Monitors

Analogue front ends (AFEs) are a set of analogue signal conditioning circuitry that are used to interface sensors to an ADC or a microcontroller. In applications like heart rate monitors, AFEs...

Smart ADC Selection Can Simplify And Improve Design

There are so many standalone and integrated analogue-to-digital converters available today. Which ADC is best for your application? How important is sampling rate or architecture type? How can you pick a...

Protection Mechanisms For Batteries And Their Charging Systems

We take batteries for granted and often use them recklessly without taking care of them and their charging systems. This results in their shorter life and sometimes outright failure when we...

Developing Microcontroller Based Product – A Case Study

If you wish to design a microcontroller-based product from scratch, here is a set of guidelines that will enable you to work from customer requirements, thru defining specifications, designing hardware, setting...

Using GaN Transistors In Power Converters

The basic requirements for power semiconductors are efficiency, reliability, controllability, and cost-effectiveness. Breakthroughs in wide-bandgap semiconductors, especially in gallium nitride (GaN), have enabled devices with high conductivity and hyper-fast switching, with...
