Working Principle

The filter module adopts a passive LC filter network structure. When the DC bus current passes through the internal inductor and capacitor combination network, high-frequency harmonic components generated by IGBT switching are absorbed and suppressed. The filter retains the DC power component while attenuating high-frequency interference signals, preventing conducted interference from propagating to the power grid or other equipment, and improving the electromagnetic compatibility performance of the entire drive system.

Installation Requirements

• Install inside the control cabinet close to the power supply module
• Use copper bus bars or large-section cables for power connection
• Ensure reliable grounding of the filter housing
• Maintain adequate surrounding space for natural convection heat dissipation
• Match the current rating with the system power configuration

Material & Structure

• Outer shell made of galvanized steel sheet with good shielding performance
• Internal integrated high-power inductors and high-voltage filter capacitors
• Standardized bus bar connection terminals for high-current transmission
• Insulating mounting brackets ensure electrical isolation from the cabinet

Usage Notes

• Do not exceed the rated voltage and power limits during operation
• Ensure correct polarity when connecting DC bus terminals
• The module must be reliably grounded to ensure filtering effect
• Do not open the housing during operation to avoid electric shock hazard
• Regularly inspect connection terminals for looseness and overheating
