International Rectifier Corp. has introduced a series of IGBTs whose improved turn-off characteristics make them a cost-effective alternative to power MOSFETs in high-frequency switching circuits, ...

International Rectifier’s (IR's) new WARP2™ 600 V 50 A, 35 A, and 20 A non-punch through (NPT) IGBTs feature improved turn-off characteristics for high-current, high-frequency switchmode power supply ...

The application of high-frequen-cy switch-mode power-supply (SMPS) technology in welding equipment has yielded many of the same benefits associated with SMPSs in other, nonindustrial designs. By ...
