IGBTs boost efficiency for white goods uses

Ixys has a new family of next generation short circuit rated IGBTs for appliance and white goods motor drive applications.

Ixys has a new family of next generation short circuit rated IGBTs for appliance and white goods motor drive applications.

These 600V, short circuit rated B2-Class medium speed IGBTs are ideal for high volume, small drive applications.

This family applies Ixys next generation IGBT technology to its short circuit rated family of 600V IGBTs to provide significant improvements in efficiency for offline small drive applications requiring this class of 600V device with switching frequency ranging up to 30kHz.

The B2-Class IGBTs have up to 25% improvement in saturation voltage and lower turn-off energy compared with Ixys prior generation of B-Class IGBTs.

These performance improvements are further enhanced by a 25% reduction in thermal resistance, providing significant increases in power handling and reliability.

Ixys' new short-circuit rated B2-Class of IGBTs offer significant reductions in conduction and switching losses, which when coupled with the improvements in thermal performance greatly extend the silicon and thus cost efficiency of these B2-Class IGBTs.

This family of IGBTs possess a lower saturation voltage with temperature, as compared with the saturation voltage of other NPT type IGBTs used for small drive applications.

Initial products will be offered for applications ranging from 10 to 40A in TO-220, TO-247 and TO-3P discrete packages, as well as surface mountable TO-263 and TO-268 packages.

Ixys has also recently taken steps to improve its manufacturing costs on all its products, including its costs for manufacture of IGBTs.

These manufacturing improvements are of particular benefit for very high volume applications, such as the cost sensitive small drive applications of the appliance and white goods markets.

Its pursuit of cost improvements has significant impact on enabling Ixys to aggressively pursue new business in these markets, for which Ixys S-B2 Class IGBTs are the first.

Additional products in the future will be developed to address the unique requirements of these high volume markets.
