IR Releases 600V Trench IGBTs To Reduce Power Dissipation In UPS & Solar Inverter Applications

March 12, 2008 by Jeff Shepard

International Rectifier (IR)® has introduced a family of 600V insulated gate bipolar transistors (IGBTs) that are said to reduce power dissipation by up to 30% in uninterruptible power supply (UPS) and solar inverter applications up to 3kW.

The new application-specific devices use IR’s latest-generation field stop trench technology to reduce conduction and switching losses, and are optimized for switching at 20 kHz with low short circuit requirements, which are said to enable higher efficiency power conversion in UPS and solar inverter applications.

"Traditionally, IGBT devices have excessive switching losses at the frequencies used in UPS and solar inverters. IR’s new Trench IGBT devices have lower switching energy coupled with low conduction losses. These lower losses provide higher efficiency, reducing the size of the unit and the cost of power generation to the end user," said Carl Blake, IR’s Product Marketing Director, Energy Saving Products.

Co-packaged with ultrafast soft recovery diodes, the new family of IGBTs is said to have lower collector-to-emitter saturation voltage (VCE(on)) and total switching energy (ETS) than punch-through (PT) and non-punch-through (NPT) type IGBTs. In addition, the internal ultrafast soft recovery diode is said to improve efficiency and reduce EMI.

Pricing for the devices begins at US$0.68 for the IRGB4059DPbF, $0.82 for the IRGB4045DPbF, $0.84 for the IRGB4060DPbF, $1.00 for the IRGB4064DPbF and $2.79 for the IRGP4063DPbF each in 10,000-unit quantities. Production orders are available immediately. The devices are RoHS compliant.
