3. Working Principle

1. Standby Blocking State: Without trigger signals, the module relies on symmetric chip bidirectional high-voltage blocking characteristics to reliably isolate the high-voltage loop, maintaining a safe off standby state without electric leakage or mis-conduction.
2. Gate Trigger Turn-on: Upon receiving standard gate trigger signals from the external drive board, the internal chip rapidly activates the conduction channel, switching the device from blocking state to low-resistance conduction state for stable main circuit current transmission.
3. High-frequency Power Conversion Operation: Performing periodic high-speed switching according to PWM timing signals, it converts power frequency power into adjustable frequency and voltage power, realizing four-quadrant operation, energy feedback and dynamic reactive power compensation functions.
4. Low-loss Steady Conduction: The optimized chip structure ensures ultra-low on-state loss and heat generation during conduction, supporting long-term stable high-power load operation and high system efficiency.
5. Active Fault Protection: The module continuously resists transient short-circuit, overload and voltage spike faults during operation. It cooperates with system protection to turn off rapidly, avoiding device burnout and fault escalation.
6. Bidirectional Energy Cycle: The symmetric structure supports reverse energy conduction and grid feedback, adapting to motor braking energy recovery and grid bidirectional power regulation to improve system energy utilization.
