Abstract :
New process technologies are extending the application range of IGBT modules. A 1400 V IGBT with significantly improved efficiency has been developed using an optimized epitaxial (punch-through) process. This new 1400 V device has a square turn-off switching SOA making it suitable for 575/608 VAC inverter applications. A very low saturation voltage 250 V IGBT has been developed using a trench gate structure. This new 250 V device offers significant size and efficiency advantages in battery powered applications including fork lift truck and UPS inverters
