pp 737-746Design for AC/DC Converter with High Power Factor Based on UC3854 * Final gross prices may vary according to local VAT. A 300W AC/DC converter with a universal input and fixed output voltage is analysed and then designed based on UC3854.The principle and structure of an active power factor corrector (APFC) and UC3854 is discussed in this paper. The experiment result shows that APFC can achieve a fixed output of 400V DC voltage in the universal input range of AC 85~265V. The designed EMI filter can effectively reduce the electromagnetic interference. And the experimental result verifies that the power supply can make the power factor reach over 0.99, and total harmonic distortion reach lower then 5%.

Additionally, there is a plethora of instrumentation, control systems, communication devices, and any number of miscellaneous electronic devices or systems in place in the background of society as a whole upon which we depend on a daily basis.

No matter what type of electronic device, be it a consumer-based product such as computers, cell phones, game systems and the like or more industrially-based OEM monitoring and control systems, they all have one common requirement for their operation– a reliable and stable source of DC power. There are three types of power conversion devices in use today: the AC/DC power supply, the DC/DC converter, and the DC/AC inverter. Of the three, AC/DC power supplies and DC/DC converters are the most commonly used. Whether an AC/DC off line power supply or an embedded DC/DC converter in a distributed power system, no other single component has as much direct effect on overall system reliability and performance as the omnipresent power supply. The power supply must not only provide reliable power to the device, but also is called upon to meet safety and emissions requirements, often while operating in harsh thermal or other less than ideal system environments. Prior to the introduction of switching power supplies to the commercial marketplace, linear converter solutions which were bulky and inefficient were the only AC/DC power supplies available.

The more efficient and compact switching type supplies became commercially available in the 60’s. Prior to that having been considered, specialized solutions were limited to aerospace and military applications. Luckily for today’s system designer, advances in virtually all component technologies including power semiconductors, integrated circuits, magnetic materials and capacitors in the more than 40 years since has led to the development of a vast array of efficient, reliable, off-the-shelf power conversion products from literally hundreds of worldwide manufacturers at economical prices. Prior to this, the designer had few packaged power converters to select from, and often had to resort to designing their own power product for use in their system. This off-the-shelf availability has freed the system designer from having to “homebrew” his or her own power supply solution and from having to contend with the myriad of safety agency requirements related to power supplies and power systems.

Power supply design and manufacturing has matured into a $25 billion industry and is now considered a specialty unto itself. Power converter designers and those firms in the business of power conversion design and manufacturing are uniquely qualified to provide the most reliable and economical solution for virtually any application. This designer’s guide seeks to acquaint the system designer with the specification and implementation guidelines for power converters. Being a key design element of any system or product, selecting the correct power converter product and required features will assure overall system performance and reliability.Microchip continues to expand its innovative 8-bit PIC® microcontrollers with Core Independent Peripherals (CIPs). These devices allow you to perform application functions autonomously in hardware instead of software. They are supported by MPLAB® Code Configurator, a free graphical programming environment that reduces development time. Our AC-DC power supply solutions can be designed to meet almost every conceivable application requirement in terms of power, performance, efficiency, communications, protection, size, approvals compliance, and cooling requirements.
