PFC Module Implements PSC Circuit Topology

Mon, 10/03/2005 - 9:16am

Fairchild Semiconductor introduces a Power Factor Correction (PFC) Smart Power Module (SPM™) to implement the Partial Power Factor Correction Switching Converter (PSC) circuit topology. By triggering the IGBTs at every half cycle of the line current, the PFC-SPM FSAB20PH60 provides 97% of power factor (typical) and full compliance with the mandatory PFC standard IEC61000-3-2. The PFC-SPM enables simpler designs by combining four rectifier diodes, two IGBTs, a gate-driving IC and a thermistor in a single, thermally efficient module. The two modules are designed to be mounted side-by-side to share a single heat sink — thus simplifying designs, speeding assembly and improving overall system reliability. The PFC-SPM's application benefits include: low thermal resistance (Rth(j-c)Q = 2.8°C/W for IGBT; Rth(j-c)Q = 2.6° C/W for diode) with the aid of DBC substrate; and low acoustic noise due to an optimized gate-driving IC.
