Main Functions

1. DC Bus High-Frequency Ripple Filtering

    

   Three built-in high-voltage capacitors absorb PWM switching ripple current on the DC link bus, stabilize bus voltage fluctuation, reduce harmonic distortion, and protect main power thyristor modules from voltage spike impact during drive switching operations.
2. High-Voltage Bus Voltage Sampling Feedback

    

   Precision resistor voltage divider circuit converts 3kV-level DC bus voltage into low-voltage analog signals and transmits them to the main control board. The CPU relies on this signal to implement overvoltage, undervoltage protection and voltage closed-loop regulation logic.
3. Safe Passive Discharge of DC Bus

    

   Integrated bleeder resistors slowly release residual high-voltage energy stored in bus capacitors after equipment shutdown, eliminating electric shock hazards during maintenance and avoiding damage to power components caused by residual voltage impact.
4. Capacitor Overheat Temperature Monitoring

    

   On-board temperature sensor tracks the operating temperature of filter capacitors. When overheating occurs due to aging or overload, the board sends fault signals to the main controller to trigger drive trip and alarm output, preventing capacitor bulging or explosion failures.
5. Isolation Signal Transmission Between High-Voltage and Low-Voltage Loops

    

   Reinforced isolation design separates high-voltage DC power loop and low-voltage control signal circuit, avoiding high-voltage breakdown and interference that cause main control board misoperation or burnout.
6. Standardized Replacement Spare Assembly

    

   Integrated combination of capacitors, sampling circuits, temperature detection and wiring terminals as one complete board. During on-site maintenance, the whole board can be directly replaced without separate matching of discrete capacitors and sampling components, greatly shortening equipment downtime.
