3. Working Principle

High-voltage Blocking in Standby State: After connected to the high-voltage main circuit, the module maintains a high-voltage blocking state without gate trigger signal, reliably withstands 4500V system high voltage, prevents leakage and false conduction, and ensures safe isolation of the high-voltage circuit.
Gate Trigger Conduction: When the matching drive module outputs +15V effective gate trigger signal, the IGCT chip conducts rapidly, the main circuit is connected, and 3500A rated large current passes stably to establish a high-voltage power channel and realize power transmission.
Steady-state Power Transmission: The device maintains ultra-low on-state voltage drop after conduction, greatly reducing steady-state operation power consumption and heat generation, adapting to long-term full-load and heavy-load continuous operation to ensure stable power output of the conversion system.
High-speed Hard Turn-off Cutoff: When circuit cutoff is required, the drive module outputs -5V turn-off voltage, the module triggers hard turn-off mechanism to quickly cut off main circuit large current, accurately respond to frequency conversion, rectification and inversion timing logic, and realize electric energy form conversion.
Fault Overload Fault-tolerant Protection: In case of grid fluctuation, load short circuit and instantaneous overload, it absorbs fault impact relying on super-large current integral withstand capacity, and quickly locks with the system protection circuit to avoid device breakdown and burnout, improving equipment fault tolerance.
Freewheeling Voltage-stabilized Closed-loop Operation: The built-in freewheeling diode discharges residual circuit electric energy in reverse, suppresses high-voltage spikes and surges, stabilizes bus voltage, and ensures stable closed-loop operation of high-voltage conversion systems without voltage oscillation.
