Smart Power Module Devices

More reliable, less parts and smaller size

These devices are designed for full-switching power factor correction in motor drive applications in the 3-6kW power range. The FPDB20PH60 (600V/20A), FPDB30PH60 (600V/30A), and FPDB50PH60 (600V/50A) all integrate two fast-recovery diodes, two freewheeling diodes, two IGBTs, a gate-driver IC, a shunt resistor and a thermistor into one package measuring 44 x 26.8 mm. They are half the size of other devices, and use 40 kHz-switching operation for less power loss, typically providing 99 percent power factor. They have under-voltage and over-current protection through integrated gate-driving IC, and offer an isolation voltage rating of 2,500 Vrms/min.

CAD/CAE Model Clean-Up: Reduce Iterative Cycles
This webinar featured research and survey results related to problems associated with preparing CAD geometry for CAE applications. We discussed how Recipe-Based Automation can help create "just-in-time" CAE-ready geometry each time a cad model is updated. Watch the Presentation

Light Matters: A High-Performance, "No-Compromise" Solid State Lamp?
First, let's define "no-compromise". In an ideal configuration, this lamp would use a high-brightness LED (HBLED) that is built into a small, integrated package, and is able to produce a large quantity of focused light, operate with a high level of reliability and generate no audible noise. Is this difficult? Yes, but it is possible.
