A World Without Cords: An Overview of Wireless Charging

A World Without Cords: An Overview of Wireless Charging

Qi (pronounced as "chee") charging is an optimized inductive charging concept also known as “wireless charging,” allowing you to charge your devices wirelessly. Compatible devices’ batteries are charged by using induction transfer without requiring separate chargers, cables or adapters... Simply place your compatible device on top of the wireless pad and watch your device charge. Finally--an end to cords!

How to Use Simple Converter Circuits

How to Use Simple Converter Circuits

Different circuit connections are explored here. For instance, an inversion of source and load converts the buck converter into a boost converter, the cascade connection of the converters leads to the formation of the buck-boost, and the Cuk converter from the basic buck and boost converters.


ARM’s New Chip Design Extends Battery Life of IoT Devices

ARM’s New Chip Design Extends Battery Life of IoT Devices

ARM is trying to resolve the thorny problem of battery life in Internet of Things devices with a new chip design that will significantly reduce the power consumed by processors, sensors and wireless chips. The company has overhauled the way it designs low-power Cortex-M chips that go into IoT devices such as health monitors, smart home devices and sensors. The restructured design could almost double battery life, ARM executives said at Computex in Taipei on Monday.
