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 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.
