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.
In the previous article, we discussed the basics of impedance matching and how to use an impedance matching transformer. Apart from using an impedance matching transformer, designers can also use Impedance Filter circuits at the output of an RF amplifier which can double up as a filtering circuit and also as an impedance matching circuit. There are many types of filter…
If you are an RF Design Engineer or anyone who has worked with Wireless Radios, the term “Impedance Matching” should have struck you more than once. The term is crucial because it directly affects the transmission power and thus the range of our Radio modules. This article aims to help you understand what Impedance Matching is from the basics and will also help you to design…
MORNSUN has introduced a new generation of DC-DC converters, the fixed input R4 series with a new packaging technology, that adopts the newest Chiplet SiP (System in Package) technology, which helps in reducing the dimension of the device by 80% and save costs for the customer. The newest Chiplet SiP technology delivers better performance and reliability when compared with…
A current transformer is a type of instrumental transformer specially designed to transform alternating current in its secondary winding, and the amount of current produced is directly proportional to the current in the primary winding. This type of current transformer is designed to non-invisibly measure current from the high voltage subsystem or where a high amount of…
Switching power supply is a widely used power supply topology in power electronics. Whether it can be a complicated CNC Machine or a compact electronic device, as long as the device is connected to some sort of power supply an SMPS circuit is always mandatory. Improper or faulty Power supply unit could lead to a big failure of the product irrespective of how well-designed…
Energy Monitors, whether covering the entire apartment or deployed to monitor just one appliance, provide a way for you to keep track of your consumption and make necessary adjustments. While they are increasingly becoming available on the market, the maker in me still feels it will be a great idea to build a DIY version that could be tailored to meet specific personal…
RICOH Electronic Devices introduced the RN5T569, a power management multichannel IC (PMIC) for automotive applications that provide four high-efficiency step-down DC-DC converters, seven low-dropout regulators, four GPIOs, an interrupt controller (INTC), and an I2C-Bus interface. The new IC can customize the power supply voltage and the power on/off sequence to meet user-…
A buck converter circuit (step-down converter) is a DC-to-DC switching converter that steps down voltage while maintaining a constant power balance. The main feature of a buck converter is efficiency, which means that with a buck converter on board, we can expect extended battery life, reduced heat, smaller size, and improved efficiency. We previously made a few simple Buck…
The STUSB4500L from STMicroelectronics is a small-footprint addition to the Company’s USB-C controller IC family designed and certified for pure 5V sink-only applications. All mandatory features to use the USB-C connector as a 5V universal power plug are integrated, allowing designers to implement USB-C charging solutions quickly and easily without…
TDK Corporation has introduced the PH600A280-24 DC-DC converter as an extension to the PH-A280 series of 200 to 425V DC input power modules from 50 to 600W. Rated at 24V 25A, PH600A280-24 has been designed to provide a wide 14.4 to 28.8V adjustment range to accommodate non-standard voltages. The device delivers an efficiency of 93% and can operate at full load with -40°C to…
The New MAX77654 single inductor, multiple-output (SIMO) power management IC (PMIC) from Maxim Integrated Product Inc, can help the designers of compact consumer devices to reduce the size of their solution by half with 20% higher battery life. The New PMIC delivers up to 3 outputs with just one inductor at 91 percent efficiency in a 19mm2 solution size, which is a 16%…
CUI Inc announced the addition of its first four contact, surface mount, non-isolated converter to its dc-dc converter line. The ultra-thin VXO78-500-M DC-DC Converter features a 500mA output current, no-load input current as low as 0.2mA and a wide -40 to +85°C temperature range. This regulated dc-dc converter offers a wide 4.75 to 36 Vdc input voltage range, short-…
