Vincotech's flowBOOST4w modules suit UPS and other three-phase PFC apps



flowBOOST4w module

Vincotech, a supplier of module-based solutions for power electronics, announced the release of its new flowBOOST4w modules designed for UPS and other three-phase PFC applications with power ratings from 100 to 200 kVA and switching frequencies from 8 to 20 kHz.

These modules serve online UPS and other applications requiring three-phase, three-level active PFC where high conversion efficiency and switching frequencies are needed to cut the size and cost of PFC chokes. Onboard capacitors prevent destructive turn-off voltage overshooting.

An optional snubber diode and a low inductive interface support switching lossregeneration. The latter also enables an ultra low inductive connection with a normal PCB board, in which case the high-power connection no longer needs to be low inductive.

The integrated NTC sensor provides a temperature signal to ensure reliable protection for the module.400 A and 600 versions are available with and without snubber diodes. Vincotech's pre-applied ultra high performance thermal interface material is optional.
