Active PFC-choke series

20 APRIL 2018

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 enamelled copper wire.
The withstand voltage value between auxiliary and power winding of the choke series is 2 kV, 2.5 kV from the two 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).
