## 12V 1A SMPS Power Supply Circuit Design

12V 1A SMPS Power Supply Circuit Design

In this tutorial we will cover how to build a 12v SMPS circuit that would convert AC mains power to 12V DC with a maximum current rating of 1.25A. This circuit can be used to power small loads or even be adapted into a charger to charge you lead-acid and lithium batteries.

Charge Pump Circuit – Getting Higher Voltage from Low Voltage Source
Boost converters are inefficient at low powers, since a lot of energy is consumed just for keeping the regulation on point and driving the power switch. Also, switch mode converters of this type are noisy – this is a problem if you’re dealing with sensitive circuitry. You’re in the uncomfortable position of an over-engineered solution. Linear regulators don’t work in reverse, so that’s ruled out as under-engineered.

How to Measure Current in a Circuit using Different Current Sensing Techniques

Current is a very critical factor in Electronics or Electrical Engineering. In electronics, current can have a bandwidth from few nano-amperes to hundreds of amperes. This range can be much wider in Electrical domain typically to several thousand amperes, especially in Power Grids. There are different methods to sense and measure current inside a circuit or a conductor. In this article, we will discuss how to measure current using various current sensing techniques with their advantages, disadvantages and applications.

Fundamentals of Motors – Theory and Laws to Design a Motor

Ever wondered how does a motor spin? What are the fundamentals involved? How is it controlled? The DC brushed motors have been in the market since a long time and they spin easily on just a DC supply/battery whereas the induction motors and permanent magnet synchronous motors involve complex electronics and control theory to rotate them efficiently. Before we even get to what is a DC motor or what are other types of motors, it is important to understand the operation of linear motor – the most basic motor. This will help us understand the fundamentals behind a motor spinning.

## Multicell Voltage Monitoring for Lithium Battery Pack in Electric Vehicles

The mileage and performance of an Electric Vehicle depends on the capacity and efficiency of its Battery Pack. To maintain the battery pack in full health is the responsibility of the Battery Management System (BMS). A BMS is a sophisticated unit in an EV which does a lot of activity like monitoring the cells, balancing them and even protecting them from temperature changes.

## 7.4V Two Step Lithium Battery Charger Circuit – CC and CV mode

The advancement in Electric Vehicles, Drone and other mobile electronics like IoT Devices seems to be promising for the future. One common thing among all these is that they are all powered by batteries. Following Moore’s law the electronic devices tend to become smaller and more potable, these portable devices should have their own source of power to operate. The most common battery choice for portable electronics today is Lithium Ion or Lithium Polymer Batteries. While these Batteries have a very good charge density they are chemically unstable under harsh conditions hence care should be taken while charging them and using them.

## Boost Converter: Basics, Working, Design & Operation

We’ve all come across pesky situations where we need a slightly higher voltage than our power supplies can provide. We need 12 volts, but have only a 9 volt battery. Or maybe we have a 3.3V supply when our chip needs 5V. That too, in most cases, the current draw is quite decent.

Eventually, we ask ourselves the question, is it possible to convert one DC voltage to another?

Lucky for us, the answer is yes. It is possible to convert one DC voltage to another, however the methods are a slightly on the clever side.

## Flyback Converter Circuit

In electronics, a regulator is a device or mechanism which can regulate the power output constantly. There are different kinds of regulators available in the power supply domain. But mainly, in the case of DC to DC conversion, there are two types of regulators available: Linear or Switching.

What are Cell Balancing Techniques and How to Use Them?

When four cells are connected in series the voltage values of all the four cells should be equal to derive the battery pack with maximum efficiency. The method of maintaining all the cell voltages to be equal is called as cell balancing. In this article we will learn more about cell balancing and also briefly about how to use them on the hardware and software level.
