Shorted-anode IGBTs provide superior switching for high-power induction heating applications

January 29, 2013 // By Paul Buckley
Fairchild Semiconductor's  high-voltage field-stop shorted-anode trench IGBTs provide designers with a highly efficient, cost-effective solution to the design challenges posed by high-power and high-frequency induction heating (IH) appliances.

Typical applications include IH rice cookers, table-top induction cookers and inverter-based microwave ovens

Ranging from 1100-1400 V, the new product family is optimized with intrinsic anti-parallel diodes for soft switching applications. With advancements over the typical non-punch-through (NPT) IGBT technology, Fairchild's shorted-anode silicon technology offers a lower saturation voltage of over 12 percent less than the same rating NPT-trench IGBT. Additionally, when compared to the competitor's IGBT offerings, this product family offers a lower tail-current rate of over 20 percent. The features allow Fairchild's advanced IGBTs to provide better thermal performance, higher efficiency and reduced power losses.

The devices high-speed switching frequency range is 10 to 50 kHz.  The FGA20S140P also claims the lowest tail-current in industry for improved switching loss .  The devices offer a low saturation voltage drop than existing NPT trench IGBTs.
