International Rectifier has introduced the IRAC1150-D2 Power Factor Correction (PFC) Control Design Kit and added a PFC design tool to the myPOWER online design centre. The Design Kit features the IR1150 µPFC for AC-DC PFC and is a small, 1.1-inch-square, fully-assembled PFC control circuit that engineers can drop in to an existing power supply, replacing its old continuous conduction mode (CCM) PFC circuit.
According to Stephen Tsang, senior vice president of sales at IR, this reference design allows designers to immediately see the benefit of IR's one-cycle control performance without a major redesign or spending a lot of time evaluating and prototyping a new PFC circuit.
Featuring IR's one cycle control (OCC) approach, the device delivers the performance of continuous conduction mode (CCM) PFC with the simplicity, reliability and low component count of a discontinuous current mode (DCM) circuit for PFC applications.
With unity PF as the ultimate goal, the IR1150 enables 0.999 PF with only 4 per cent total harmonic distortion, enabling AC-DC applications to conform to international legislative requirements such as IEC 1000-3-2 in Europe, JIC C 61000-3-2 in Japan and the China Compulsory Certificate (CCC) for products using more than 75W. As manufacturers implement PFC in response to these energy standards, the IR1150 control IC simplifies effective PFC solutions, and enables a single design that can be used worldwide.
The IR1150 µPFC control IC, offered in a compact SO-8-package with a lead-free option, cuts PFC control board space as much as one-half, and enables a simplified and flexible high density solution for computing, consumer electronics and home appliances from 75W to 4kW.
The IRAC1150-D2 reference design board is available immediately. Pricing is US$195 each and is subject to change. The on-line PFC design tool is available at no charge, after registering on the myPOWER design centre, at http://mypower.irf.com
