Intelligent Interleaving: improving energy efficiency in AC-DC power supplies
From Fairchild Semiconductor, a how-to on improving energy efficiency in your power supply design using the FAN9612 Interleaved Dual Boundary Conduction Mode PFC controller.
Efficient power systems for portables
The performance of power supplies for portable systems need to be improved on a constant basis. This how-to from Ittiam presents a generic power supply design for an embedded system and examines the function of each module in the design. It provides guidelines for selection of topologies and components, thermal and packaging aspects and even battery management.

Motor control in air conditioners with dual sensor less FOC and active PFC
Improved energy efficiency and reduced system costs are the driving factors in modern motor control designs. Sophisticated motor control concepts with sensor less Field Oriented Control (FOC) and Power Factor Correction (PFC) help to fulfill these demands. The article shows how these concepts can be used in an air conditioner design for vehicles.
Current/voltage measurement accuracy enables wind-turbine efficiency
Wind power is fast becoming a reliable source of alternative energy. Driven by large multi-megawatt wind turbines, the market for wind power inverters is growing. This piece from Avago investigates how these power inverters work in this environment.
