Pulse Electronics Corporation has expanded its P0584/85NL high-isolation gate drive transformer line with a new series that uses insulation wire on all windings, making them compliant to safety standards such as IEC61558 and IEC60601 for reinforced isolation. The P0584/85NL series provides isolation in MOSFET and IGBT drivers in industrial applications such as motor drive circuits and solar inverters and for power supplies for a range of medical devices. The P0584/85ANL versions extend these to applications that require higher levels of safety and isolation with 30% increased isolation capability (to 4250Vrms) and 20% greater volt-second capability.

“Existing toroidal gate drive transformers with triple insulated Teflon wire on just one winding are not compliant to certain safety standards which require mechanical support between windings, even when triple insulated wire is used on one winding,” explained Gerard Healy, product manager, Pulse Electronics Power Business Unit. “Pulse’s new P0584/85ANL series uses insulated wires on all windings, making them fully compliant. In addition, by using smaller wire diameters, Pulse can increase the number of turns to increase volt-second capability within the same platform size.”
