CM900HG-130X Circuit Diagram

This circuit diagram for the CM900HG-130X shows the internal structure of a high-power IGBT module comprising three IGBT units connected in parallel. Each IGBT is paired with an anti-parallel freewheeling diode to handle inductive load currents and ensure safe operation during switching. The module has three emitter terminals (1, 3, and 5) and three corresponding collector terminals (2, 4, and 6), representing the three parallel IGBT-diode pairs. These are internally connected to share the current evenly, improving thermal performance and current handling capability.

The gate terminal (G) is common for all three IGBT units, allowing them to be controlled simultaneously. Similarly, the emitters are connected to a common emitter pin (E), simplifying external circuit design. This configuration is optimized for high-efficiency switching applications, such as inverters, motor drives, and power conversion systems, where high current handling and fast switching are critical. The integrated layout also enhances reliability and reduces the need for external wiring.
