True three-phase high-spec power factor correction module for AC/DC supplies

SynQor’s latest mil-spec power factor correction (PFC) modules are now available from Luso Electronics. The MPFC-115-3PH-270-FP module is a building block for three-phase input AC-DC power conversion in an industry standard full-brick package (2.5 x 4.7 x 0.5in) for defence, aerospace and commercial applications. When used with SynQor's half-brick AC line filter, a hold-up capacitor and SynQor's high efficiency Mil-COTS DC-DC converters, the system draws 'nearly perfect' and well-balanced sinusoidal line currents (PF>0.99) from a three-Phase AC-DC input. The complete front-end system is designed to comply with MIL-STD-704, MIL-STD-1399 and MIL-STD-461 and MIL-STD-810G, says the company. Delivering 1500W of continuous output power with peak power capability of 2000W, the module provides a nominal semi-regulated 270 Vdc output with efficiency at 94%. It also has a feature to access the mid-bus voltage (loosely regulated 205VDC nominal) which if utilised as the primary output increases the overall efficiency of the module to over 95%. The module is a true three-phase PFC module, not a composite of three single-phase PFC modules. It can operate at full power from -55C to +100C baseplate temperature, and it is ideal for harsh environments seen in many defence / aerospace applications, says the company.
