New IGBT Co-Packs From International Rectifier Reduce Conduction Losses By Up to 25% While Improving Ruggedness In Motor Drives
EL SEGUNDO, CA. October 2001 - International Rectifier, IR® (NYSE: IRF) introduces the new M Series family of 600V short-circuit rated IGBT/FRED Co-Pack devices for sub-two-horsepower industrial and appliance motor drives.
The new devices offer 18% lower saturation voltage, or VCE(ON), than previous generation short-circuit rated devices and have the lowest VCE(ON) for short-circuit-rated Co-Pack IGBTs on the market. The lower saturation voltage reduces conduction losses by up to 25% at 50% duty cycle operating conditions, allowing designers to reduce heat-sink size to achieve more compact and cost effective designs.
The M Series devices further simplify design and reduce circuit size thanks to their simplified driver requirements. The short-circuit capability protects the devices during circuit faults or abnormal operation for improved ruggedness of the motor drive.
"The new M Series IGBTs are an excellent alternative for compact, efficient, cost-effective and rugged motor drives for sub-two-horsepower applications," said Alberto Guerra, Director, Motor Drive Sector Management.
Technical Details
The M Series Co-Pack IGBTs, IRG4BC15MD, IRG4BC20MD and IRG4BC20MD-S, offer a VCE(ON) as low as 1.85V at 100°C and have a 10µs short circuit capability at full 15V gate drive (VGE) input. The new M Series devices are optimized to minimizing switching losses in the 4-10kHz operating frequency range.
The M Series 600V Co-Pack IGBTs are specifically designed for use in the bridge configurations typically found in motor drives. The IGBTs are co-packaged with HEXFRED® ultra-fast, ultra-soft recovery anti-parallel diodes. The ultra-fast, ultra-soft diode recovery reduces or eliminates snubber components and minimizes switching losses as well as noise and EMI.
The M Series IGBTs feature very low shoot-through current in the absence of turn-off bias unlike other IGBTs available on the market. As a result, they simplify the drive circuit by eliminating the need for a negative bias power supply. The M Series IGBTs can easily be used with high voltage gate driver ICs such IR21xx Series to further simplify circuit design and cut circuit size.
"IR offers IGBTs with optimized switching speeds that enable the designer to select the best device for the particular topology and operating frequency. The M Series offers the best short-circuit rated performance in the 4 to 10kHz range," added Guerra.
Pricing and Availability
The new Co-Pack IGBTs are available now. Pricing for the new devices begins at US $1.10 each in 10,000-unit quantities. Data sheets are posted on the International Rectifier Web site, www.irf.com.
