3-Phase 1500W Power Factor Correction Module

SynQor, Inc. announces the release of the newest addition to its family of Power Factor Correction Modules: the MPFC-115-3PH-270-FP. This module is a power factor correction building block for 3-phase input ac-dc power conversion in an industry standard full-brick package (2.5" x 4.7" x 0.5").

When the MPFC‑115‑3PH‑270‑FP is used with SynQor's half‑brick MACF‑115‑3PH‑UNV‑HT AC line filter, a hold‑up capacitor and SynQor's high efficiency Mil‑COTS DC‑DC converters, it draws nearly perfect and well balanced sinusoidal line currents (PF>0.99) from a 3‑phase ac input. This provides the design engineer with the building blocks for a complete front-end system that is designed to meet MIL‑STD‑704 (A‑F with leading PF), MIL‑STD‑461 (C,D,E,F), MIL‑STD‑1399 and MIL‑STD‑810G.

The MPFC‑115-3PH‑270‑FP delivers 1500W of continuous output power with peak power capability of 2000W. The module accepts 3‑phase input voltage range of 85- to 140- Vrms L‑N (147- to 242-Vrms L‑L), 45‑800 Hz. The module provides a nominal semi‑regulated 270Vdc output with efficiency at 94%. The module also has a feature to access the mid‑bus voltage (loosely regulated 205Vdc nominal) which if utilized as the primary output increases the overall efficiency of the module to >95%.

This first of its kind module is a true 3‑phase PFC module, not a composite of three single‑phase PFC modules. It can operate at full power from ‑55 to +100 degrees C baseplate temperature, and it is suited for harsh environments seen in many Military/Aerospace applications, especially those working to meet SWaP‑C2 requirements.

The features and protections of the MPFC‑115‑3PH‑270‑FP can be found in the datasheet. One special feature of note is a Battle Short provision, which allows for the override of certain protection features for mission critical applications. SynQor's MPFC‑115‑3PH‑270‑FP and MACF‑115‑3PH‑UNV‑HT are available for immediate evaluation and purchase.
