True 3-phase mil-spec Power Factor Correction module for AC-DC supplies
The MPFC‑115‑3PH‑270‑FP module is a building block for 3‑phase input AC‑DC power conversion in an industry standard full‑brick package (2.5 x 4.7 x 0.5in) for military, 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 3‑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.
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 205 Vdc nominal) which if utilised as the primary output increases the overall efficiency of the module to over 95%.
This 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°C to +100°C baseplate temperature, and it is perfectly suited for harsh environments seen in many military/aerospace applications. 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 full portfolio of mil-spec PFC modules are available for evaluation and purchase from Luso Electronics in the UK and Ireland.
