WebThis table describes the characteristics of the IGBT during switching from on to off and vice versa. The CIES capacity is to input, between Gate and emitter. It is important because each time the IGBT is turned on you should charge the capacitor and each time the IGBT is turned off you must download it.

WebAs the IGBT is generally used for switching, it is important to fully understand the turn- on and turn -off switching characteristics in order to determine “switching loss” (power dissipation loss at switching). It is also important to remember that these characteristics are affected by various parameters when determining operating conditions.

WebWhile an IGBT is a voltage drive type element, charge/discharge for input capacity (Cies) is needed to turn on and off the gate because of the presence of capacity between the individual terminals as shown above. Therefore, switching an IGBT needs a gate charge/discharge circuit.
WebQuesta tabella descrive le caratteristiche dell’IGBT durante la commutazione da acceso a spento e viceversa. La capacità CIES è quella di ingresso, tra Gate ed Emettitore. È importante perché ogni volta che l’IGBT viene acceso occorre caricare tale condensatore ed ogni volta che l’IGBT viene spento occorre scaricarlo.
