In this article, we will be making an IoT-based pre-paid electricity system and learn exactly how that works. We will create a meter that will monitor the electricity usage and report to a monitoring server (which we will also create) for bills. In an ordinary electricity system, bills come after the usage, and then we…

Power semiconductors based on silicon carbide (SiC) offer several advantages like high efficiency, power density, voltage resistance, and reliability. This creates opportunities for new applications and improved charging station technology innovations. Infineon Technologies announced a collaboration with Infypower, a Chinese provider of new energy vehicle charging. Infineon will provide INFY with the industry-leading 1200 V…

Battery electric vehicles (EVs) have showcased rapidly growing sales figures over the last several years. There are several reasons to consider an EV aside from saving on gasoline. The prominent one, of course, is the environment. EVs have no tailpipe emissions, and research shows that they’re responsible for lower levels of greenhouse gases (GHGs) than…

STMicroelectronics, a global semiconductor provider serving customers across the spectrum of electronics applications, has revealed a wireless power receiver with the industry’s highest available power rating of 100 Watts. Ensuring the fastest wireless charging times in the market today, ST’s new STWLC99 device can recharge high-end smartphones with the largest battery capacity in less than 30…

With the rising number of mobile devices, notebooks, and battery-powered equipment, the need for increased charging power and fast charging has emerged. For engineers, this trend poses the challenge of achieving ever-higher power levels in smaller form factors while simultaneously meeting thermal performance requirements. To address these contemporary design needs, Infineon Technologies combines the hybrid…

Battery systems for 48V are used in multiple, growing market categories including mild hybrid electrical vehicles, trucks, e-wheelers, and battery packs for solar panels. However, these Li-ion battery systems need to be protected against negative and positive voltages. In addition, these batteries must quickly and reliably disconnect from loads within microseconds in the event of…

Infineon Technologies AG has developed a security solution for automotive wireless charging. OPTIGA Trust Charge automotive complies with version 1.3 of the Wireless Power Consortium (WPC) Qi standard, which requires strong cryptographic authentication for wireless charging up to 15 W. For this, the power transmitter must authenticate itself to the power receiver, such as a cell…

STMicroelectronics’ STWLC98 integrated and wireless power receiver delivers faster wireless charging and flexible charge sharing for diverse portable and mobile devices for home, office, industry, healthcare, and in-car applications. When combined with the STWBC2-HP transmitter IC, the complete transmitter-receiver system can deliver up to 70W on the receiver end at high system efficiency. The STWLC98…

The Wireless Power Consortium (WPC) recently released the Qi 1.3 specification that requires authentication for improved safety when transmitting up to 15W of power between a transmitter and a receiver. To meet the requirements of the specification, Microchip Technology announced a new Qi 1.3 wireless charging reference design that provides developers of wireless charging systems for…

What is a Capacitor? A capacitor is a passive two terminal component which stores electric charge. This component consists of two conductors which are separated by a dielectric medium. The potential difference when applied across the conductors polarizes the dipole ions to store the charge in the dielectric medium. The circuit symbol of a capacitor…
