FRED Pt ® DIODES
PFC Capabilities
Introduction
Power factor correction (PFC) can be defined as the reduction of the harmonic content induced in the AC distribution
net. An appropriate circuit is often required to reduce this kind of disturbance. PFC can also be thought of as aligning the
phase angle of the incoming current with respect to the voltage waveform, thus maximizing the real power drawn from the
AC line.
Regulatory Drivers
With widening applicability of the harmonic reduction standard, more power supply designs are incorporating PFC
capabilities. Different PFC regulations and standards have recently arisen, resulting in the following regulations:
• Europe – EN 61000-3-2
• UK – BSEN 61000-3-2
• Japan – JIC-C-61000-3-2
• China – CCC (China Compulsory Certificate)
Other standards apply in different ways to PFC circuits, especially in regards to efficiency, such as EPA Energy Star and
80 PLUS®.
Topology Choices
The active PFC option is a well-established solution as it allows designers to meet regulatory requirements with minimal
effort. Moreover, it provides other benefits such as simplifying the main power conversion stage and eliminating the
number of bulky components.
A boost converter provides a natural means for achieving a high power factor because of the inductor being present on
the input side. This inductor allows the shaping of the input current to be in phase with the line voltage.
Key Benefits
• Highest system efficiency compared to other hyperfast diodes
• Lowest switching losses for CCM PFC products with reduced ringing up to the highest di/dt to limit EMI
• Lowest VF conduction losses for DCM PFC dedicated products
Applications
• Server power supplies
• High-end desktop power supplies
• Telecom power supplies
• Solar inverters
• Notebook adaptors

PFC Capabilities
DCM, CRM, or CCM?
A boost converter can operate in two modes: continuous conduction mode (CCM) or discontinuous conduction mode
(DCM). The mode is defined by the current flowing into the boost inductor:
• DCM – Suitable for low- to medium-power applications due to reduced switching losses
(forward voltage is a critical parameter)
• CRM – Border mode operation combines high efficiency maximizing the usage of inductive elements
• CCM – Better suited for medium- to high-power applications. Peak currents are lower, which reduces switching
losses and requires less filtering (reverse recovery charge is a critical parameter)
