Abstract:
New IGBT and Diode chip generation in 3300V voltage class with an enhanced bonding technology is depicted in this paper. Field proven Trench gate structure in combination with a robust VLD/DLC edge termination, adopted from the 6500V chip technology, forms the basis of IGBT4 chip technology. The EC4 Diode is further improved to achieve 200mV of reduced forward-voltage drop without compromising the cosmic radiation robustness. Combination of new chip technology with enlarged chip area, reduced thermal resistance and an enhanced bonding technology forms the new 550A/3300V half-bridge module to deliver an increased rms current by 30% to 40%. Applications like traction converters, special-purpose medium-voltage drives, and commercial agriculture vehicles (CAV) demands higher power cycling capability to achieve an optimized cost performance ratio for their next generation converter platforms.
