New HVIGBT modules for more compact inverters
Mitsubishi Electric has developed eight new X-Series HVIGBT modules in three classes for larger capacity and smaller sized inverters in traction motors, DC-power transmitters, large industrial machinery and other high-voltage, large-current equipment.

The new X-Series HVIGBT module (6.5kV/1000A) features a seventh-generation insulated gate bipolar Transistor (IGBT) and relaxed field of cathode (RFC) diode,.

 

Product Features include a wide range of new high-voltage IGBTs includes leading power-capacity ratings, contributing to the large capacity of inverters
- Three 3.3kV modules (one 1200A and two 1800A models), three 4.5kV modules (900A, 1350A and 1500A models) and two 6.5kV modules (600A and 900A models)

Two modules offering industry-leading power capacity ratings — 1800A in the 3.3kV module and 1500A in the 4.5kV module — join another leader, the existing 6.5kV module (1000A rating)

 

The seventh-generation CSTBT chip and RFC diode chip reduce power loss by about 20%, Mitsubishi claims. The new chip set’s reduced package size, about 33% smaller than its predecessor will lead to smaller inverters 
150-degree Celsius operating temperature enables a simplified cooling system which realizes smaller 
inverters and improves the degree of freedom in design.

The package’s new internal structure achieves longer lifetime through improved heat dissipation, moisture resistance and flame retardance.

The new models will be released sequentially beginning in September.
