IGBTs tackle 600V UPS, solar, motor, and welding applications
Bill Schweber, EE Times -- EDN, January 5, 2012
Using a trench-insulated process, two new IGBTs
(insulated-gate bipolar transistors) from International
Rectifier provide fast switching, ease of parallel
configuration, and 600V ratings, meeting
the needs of higher-power UPS systems, solar
power, motors, and welding applications.
The IRGP4067DPbF and
IRGP4066SDbF feature low conduction
and switching losses,
along with a low-reverse-recovery-charge diode for soft
switching. The IGBTs can switch at
8 to 30 kHz and have a 5-μsec short-circuit
rating. Their low voltage drop
and a positive-voltage-drop temperature
coefficient facilitate using these IGBTs in parallel
for high-power, low-resistance designs.Breakdown voltage is 600V, with a charge current of 120A at 100°C for the IRGP4067DPbF and 75A for the IRGP4066SDbF. Both have a 1.9V voltage drop. Thermal resistance is 0.20°C/W for the IRGP4067DPbF and 0.33°C/W for the IRGP4066SDbF. The IRGP4067DPbF comes in a super TO-247 package and sells for $5.58 (10,000); the IRGP4066SDbF comes in a standard TO-247 and sells for $4.80.
