Shorted-Anode IGBTs Provide High Reliability And Superior Switching
High-power and high-frequency induction heating appliances require lower conduction losses and superior switching performance in order to achieve higher efficiency and system reliability in applications such as IH rice cookers, table-top induction cookers and inverter-based microwave ovens. Fairchild's high-voltage field-stop shorted-anode trench IGBTs provide designers with a highly efficient, cost-effective solution to these design challenges.
