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!
Converter Evaluation and Design
List of common converters and calculations of switch stresses/utilization are presented in this article. Converter design with the aid of computer spreadsheet is also shown here. A short list of converters is provided based on the basic topologies and circuit manipulations of the converters discussed on other technical articles.
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.
