New lighting ballast design software

25 January 2006 Design Automation

International Rectifier has introduced Version 4.0 of its ballast design assistant software, which it claims reduces electronic ballast design time, producing a schematic and complete bill of materials.

New features in the IRPLBDA4 version include support for DC input voltage applications and a new time domain graph feature. The new graph feature is based on a simplified numerical analysis technique, and shows ballast output waveforms including the half-bridge voltage, lamp voltage and current and resonant inductor and resonant capacitor current. Also included is an inductor calculator that creates winding specifications for the resonant output inductor as well as the power factor correction inductor if used.

The software generates designs for IR's recently-introduced IR2520D compact fluorescent lamp (CFL) ballast control IC and the IR2161 intelligent control IC for low-voltage halogen lamp transformers in addition to other IR electronic ballast ICs.
