New Generation of High-Power IGBT Modules
IGBT applications are rapidly expanding. Since they make possible higher efficiency and quieter
operation of equipment such as general-purpose inverters, uninterruptible power supplies, and welders,
IGBTs are now used in many diverse application areas. Recent development of 3.3 kV high-voltage IGBT
modules expands their scope of applicability to fields such as traction motor control. Building on this
experience, Hitachi presents a new, expanded range of high-power IGBT modules suitable for a variety of
Inherent Design Concepts
High performance and high reliability combined with the use of improved ultra-soft and fast-recovery
diodes are the underlying reasons why Hitachi high-power IGBT modules offer reduced power losses and
noise that results in higher operating efficiency.
