The high demand of "passive PFC choke series" and the demands of our customers for greater achievements enables HAHN to present now the "active PFC-choke series".
The "active PFC-choke series" takes place in the circuit topologies DCM (Discontinuous conduction mode) and CCM (Continuous conduction mode) application and meets the requirements of the major manufacturers of power regulators. It will be implemented in the pot core design PQ, which acquires highest efficiency in its small dimensions. The new choke series includes an inductance ranging from 50µH to 1000µH, divided into appropriate intermediate steps. This current value of 1.5 A to 16.5 A can be achieved with a frequency response of 500 kHz. The "Active PFC-choke series" is characterized by very high impulse withstand voltage due to the use of high-quality enameled copper wire, so that intermediate circuit voltages up to 600 V / DC are easily possible.
The withstand voltage value between auxiliary and power winding of the choke series is 2 kV and 2.5 kV from windings to the core. Furthermore HAHN sets on UL listed materials, corresponding to the insulation class F (155 ° C). In addition, these materials are compliant to the HAHN insulation system HAHN 155-2 (E237745). We also generate solutions, which exactly meet your requirements. The development team and the technical support of HAHN will be happy to help you.
