With the advent of Electric Vehicles and Internet of things the need for sophisticated power electronic design has increased. These new fields are constantly evolving the demands for high-power motor drives, energy efficient power supplies, wireless power transfer etc.
In this section we will design and test various power electronic projects for a wide variety of applications including EV, Solar, IoT, SMPS Power supplies, LED Drivers, Portable power supplies etc. The section also covers the latest power electronic news and articles to update the readers with latest technology trends.
Voltage Follower is simply a circuit in which output follows the input, means output voltage remains same as input voltage. It is also commonly known as Unity gain Opamp Amplifier or Opamp Buffer. Here we construct a voltage follower using Opamp LM741 and see how its output follows the input. We already discussed about it in our Non-inverting Operational Amplifier tutorial,…
ON Semiconductor released two new products to be used together in USB Type-C applications while offering benefits in other modern power-oriented applications. The new devices are the FSA4480, a USB Type-C analog audio switch with integrated protection, and the NCS21x series of current sense amplifiers.
The FSA4480 is a high-…
Solenoids are very commonly used actuators in many process automation systems. There are many types of solenoids. For instance, there are solenoid valves which can be used to open or close water or gas pipelines, and there are solenoid plungers which are used to produce linear motion. One very common application of a solenoid that most of us would have come across is the…
In the previous tutorial, we demonstrated detailed design of Boost Converter using MC34063, where a 3.7V to 5V boost converter was designed. Here we see how to convert 12V to 5V. As we know that exact 5V batteries are not always available, and sometimes we need higher voltage and lower voltage at the same time to drive different parts of circuit, so we use higher voltage (…
Power electronic switches like BJT, SCR, IGBT, MOSFET, and TRIAC are very important components when it comes to switching circuits like DC-DC converters, Motor Speed Controllers, Motor Drivers, and Frequency Controllers etc. Each device has its own unique property and thus they have their own specific applications. In this tutorial we will learn about the TRIAC, which is a…
Managing and reducing power consumption is crucial in low-voltage, high-power applications such as FPGAs, Graphics Processing Units and embedded systems. Before these devices can manage the power consumption, they first need to accurately measure the consumption from different rails, which is generally costly and need multiple ICs and power configurations. To meet these…
Different Electronic systems operate in different level of voltages. Most commonly the digital electronic systems like microcontrollers and microprocessors operate in 5V or 3.3V. Industrial Level Control devices like PLC, HMI etc. have an operating voltage of 12V, 24V etc. The loads (LED indicator) and sensors, that are used to interface with a PLC, also have a nominal…
Wireless Charging is the process of recharging battery powered electronic devices without directly tethering them using wires and cables to a power source. The process gives users the freedom of charging their phone on the go without the need to plug to power outlet. This means wireless charging enabled smartphones and other devices could be charged by simply placing them on…
Power-management ICs offer high performance, small size, efficiency, and protection needed by advanced auto subsystems
With a series of power management ICs (PMICs) from Maxim Integrated, designers can optimize power for automotive advanced driver-assistance systems (ADAS) functions to achieve high performance, small size, efficiency, and electrical protection.

In modern days, Lithium batteries are enriching the electronics world. They can be charged very fast and provide good backup, which along with their low manufacturing cost makes lithium batteries the most preferable choice for portable devices. As a single cell lithium battery voltage range from minimum 3.2 voltage to 4.2V, it’s difficult to power those…
STMicroelectronics develops STUSB4500, a standalone USB Type-C and Power-Delivery controller to aim an easy migration to Type-C USB interfaces in a wide range of consumer, industrial, and medical products. It is a certified standalone USB power-delivery controller optimized for sink-only applications powered through a USB-C cable and can easily be customized by the end-…
RECOM released its RAC05-K/480 series 5W AC/DC converters which accept input voltages of up to 480VAC. OVC-III rated with a 6kV surge protection, they operate reliably at industrial temperature ranges and a good fit for housekeeping operations in Industry 4.0, smart automation applications, smart grid, renewable energy, smart metering, and IoT applications that require low…
