Thanks to the lower collector to emitter saturation voltage and turn-off losses, the “V” family is suitable for all high frequency applications, such as:
High frequency motor drive (industrial and silent applications);
Power Factor Corrector for motor drives;
Induction heating and cooking (zero voltage
Lighting (HF applications).
"V"
Series IGBTs Benefits |
In the "V" series E
on will give the IGBT turn-on losses including the reverse recovery energy of the fast diode, as follows:
|
from t 1 (10% of V GE) to t 2 (5% of V CE). |
If the IGBT is offered with a co-packaged diode (for example
STGW20NC60VD) the diode is used as an external diode for the switching energy measurements. It must be noted that the E
on value is independent of the IGBT temperature and increases when the external diode is at 125°C. In the E
off measurement we extend the integration until the voltage becomes flat and the current is equal to zero in order to include the current tail. Both the IGBT and diode are at the same temperature (25 and 125°C) during turn-on and turn-off measurements, with the conditions: V
CC = 390V, IC = I
NOM, V
GE = 15V, R
G= 3.3 Ohm.
