A new range of IGBTs is optimised for induction heating applications.
The IXG(Q,P)20N120B/IXG(Q,P)20N120BD1, IXG(Q,P)28N120B/IXGQ28N120BD1 and IXGQ35N120BD1 are optimised to provide minimal power dissipation in the power switches of induction heating circuits.
The design of these IGBTs was also selected to provide the best possible cost and price options for induction heating circuit designers through Ixys' selection of package options.
Design of IGBTs for specific performance criteria requires a compromise between saturation voltage and switching speed, the main contributors to power dissipation in power switches.
These IGBTs use Ixys' proven punchthrough (PT) technology, with the design for switching speed versus saturation voltage selected to provide the best compromise possible between minimising the conduction losses generated by saturation voltage and the turn-off switching losses largely driven by switching speed.
Other benefits of Ixys PT IGBTs include higher surge current capabilities, and a saturation voltage with a negative temperature coefficient, reducing conduction losses with increasing temperature.
These devices are ideal for medium switching frequency applications (up to 30kHz) in hard-switching applications and up to 100kHz in resonant applications.
These IGBTs can reduce waste heat and improve efficiency in various applications, particularly induction cooking and heating.
The addition of the D1 ending for the respective part numbers denotes a device that incorporates an ultrafast-recovery epitaxial diode (FRED).
Ixys copack IGBTs, IXG(Q,P)20N120BD1, IXGQ28N120BD1 and IXGQ35N120BD1, exhibit very low reverse recovery charge, which further increases the efficiency improvements gained by use of Ixys PT IGBTs.
The diode provided in these IGBTs for induction heating were selected to meet the needs of designers for these applications, while minimising the additional cost and the resulting price to end customers.
Even the choices of packaging - in this case the cost-efficient TO-220 andTO-3P - were selected to meet the requirements of the circuit designer in terms of price and performance.
Samples of all products are available now.
