Design UCD3138 controlled interleaved PFC

Posted: 27 Oct 2014     Print Version  Bookmark and Share

Keywords:UCD3138  power supply controller  power conversion  power factor correction  PFC 

The UCD3138 is a digital power supply controller from Texas Instruments. The flexible nature of the UCD3138 makes it suitable for a wide variety of power conversion applications. In addition, multiple peripherals inside the device have been specifically optimised to enhance the performance of ac/dc applications such as a power factor correction (PFC).

The UCD3138 is a fully programmable solution offering customers complete control of their application. However, the use of digital controllers in PFC design brings new challenges to many analogue designers in their effort to change the design from the analogue space to its new digital environment. This application note gives a step by step guidance of how to design a UCD3138 controlled interleaved PFC. It covers hardware interface, voltage loop and current loop implementation, protection, firmware structure, internal state machine, as well as some advanced features. Finally, a graphical user interface (GUI) and how to tune a new designed PFC are presented.
