SCALE-2 1SC0450E SCALE-2 1SC0450E Preliminary Description & Application Manual Single-Channel Cost-Effective Driver Core for IGBTs up to 4500V and 6500V Abstract The 1SC0450E single-channel SCALE-2 driver core combines unrivalled compactness with broad applicability and cost-effectiveness. It is designed for industrial and traction applications requiring high reliability. The 1SC0450E drives all usual high-voltage IGBT modules up to 4500V and 6500V. Up to four parallel-connected IGBT modules can be driven to cover higher power ratings. Multi-level topologies involving 3300V or 4500V IGBTs with higher isolation requirements can also be easily supported by the 1SC0450E. The 1SC0450E supports maximal design flexibility as no fiber-optic links are assembled on the driver board. Gate drive input and output signals are provided over dedicated electrical interface connectors. The 1SC0450E is the most compact driver core in its voltage and power range, featuring a footprint of only 60mm x 90mm and a maximum insertion height of 27.5mm. It allows even the most restricted insertion spaces to be efficiently used.
