ON Semiconductor updates Power Factor Correction Handbook to provide new design resource

Business news |
By eeNews Europe

The handbook is a useful tool for engineers engaged in power system design and looks at the fundamental theory behind PFC and the key considerations that need to be addressed when implementing power factor control.      

Various PFC approaches, such as Continuous Conduction Mode (CCM) PFC, Interleaved PFC, Bridgeless PFC, and Single Stage Isolated PFC are evaluated. The handbook will help engineers optimize their power system designs for specific application criteria, thereby enhancing overall power performance.      

Content Includes:    

  • An overview of different PFC topologies: Critical Conduction Mode (CrM), Continuous Conduction mode (CCM), Frequency Clamp Critical Conduction Mode (FCCrM), Bridgeless, Interleaved, Single Stage  
  • Comprehensive analysis of PFC operating modes  
  • Detailed comparison between these different types of PFC implementation.    

“Power supply design is becoming increasingly challenging as demands for integrated power factor correction, higher active efficiency, and lower standby power consumption must be aligned with greater levels of functionality,” said Christophe Warin, ON Semiconductor’s AC-DC business unit manager. “Simultaneously, there is growing pressure for home and office electronics to comply with more stringent environmental guidelines, such as ENERGY STAR. By employing the PFC techniques described in this handbook, OEMs will be able to realize major improvements in overall energy efficiency levels, and rapidly bring products to market that meet global performance benchmarks.
