CHANDLER, USA: Microchip Technology Inc., a leading provider of microcontroller and analog semiconductors, announced the Digital Interleaved Power Factor Correction (PFC) Reference Design, which demonstrates how to realize the benefits of fully digital PFC for green power-supply designs.
Specifically, this free reference design provides an easy method to evaluate the power efficiency and features of Microchip’s dsPIC33 “GS” series of Digital Signal Controllers (DSCs) for Switch Mode Power Supplies (SMPSs), in an interleaved PFC application.
The trend toward digital power conversion is enabling green power-supply designs, along with smarter and more efficient power systems. This trend helps to lower the carbon footprint of power systems and ease the burden on the world’s strained power grids. High-performance power supplies are used in a wide variety of applications, including telecom and industrial equipment, digital TVs, lighting, air conditioners and other home appliances.
Digital interleaved PFC improves the power supply’s overall efficiency, along with the input power factor, voltage regulation and the Total Harmonic Distortion (THD) of the input current.
“This reference design enables our customers to quickly bring the benefits of digital interleaved PFC to their products, and create a more efficient and greener power distribution grid,” said Sumit Mitra, vice president of Microchip’s High Performance Microcontroller Division. “It uses the flexible dsPIC33F 'GS' series of DSCs, which enables easy customization and configuration via simple modifications to the control software.”
