CM1600HC-34H Circuit Diagram

This circuit diagram of the CM1600HC-34H depicts a dual Insulated Gate Bipolar Transistor (IGBT) module with anti-parallel freewheeling diodes. Each IGBT has three terminals: collector (C), gate (G), and emitter (E). The diagram shows two IGBT switches connected in a half-bridge configuration, which is common in high-power inverter and motor drive applications. The gates of both IGBTs are individually accessible, allowing for independent switching control. The emitters are also brought out separately, providing flexibility for sensing or protection circuits. The anti-parallel diodes across each IGBT allow current to flow in the reverse direction during switching operations, which is essential for handling inductive loads and ensuring efficient energy recovery. This setup enables the module to manage high voltage and current with fast switching capabilities and reliable protection features.
