ABB PMKHRMBRC3000B
The ABB PMKHRMBRC3000B is a high-performance harmonic filter module in the ABB M2M series, specifically designed for industrial power systems to suppress harmonic interference and improve power quality. This module is suitable for scenarios such as variable frequency drives (VFD), UPS systems, data centers, and new energy power generation (e.g., photovoltaic inverters). It can effectively reduce the grid harmonic distortion rate (THD) and ensure compliance with international power quality standards such as IEEE 519 and IEC 61000-3-12.
The PMKHRMBRC3000B adopts either Active Filtering Technology (APF) or Passive LC Filter Design (depending on the model suffix). It dynamically compensates for characteristic harmonics such as the 3rd, 5th, and 7th orders, while providing Power Factor Correction (PFC) functionality. Its core value lies in enhancing grid stability, protecting sensitive equipment from harmonic damage, and reducing energy loss.

Structure and Composition
Active Filter Version (if applicable):
IGBT Inversion Unit: High-frequency switching devices (such as SiC MOSFET) that generate reverse harmonic currents in real-time.
DSP Control Board: Based on a digital signal processor (DSP), it quickly analyzes harmonics and calculates compensation strategies.
Current Transducer (CT): Monitors the harmonic components of the load current in real-time.
LC Filter Circuit: Filters out the inverter's own switching noise.
HMI Interface: A touch screen or LED panel that displays parameters such as THD and load rate.
Passive Filter Version (if applicable):
Composed of a tuned reactor and a capacitor bank, designed for specific harmonic frequency bands (e.g., 5th, 7th orders).
Main Features and Advantages
Efficient Harmonic Suppression:
The active type can dynamically compensate for full-frequency harmonics (2-50th orders) with a suppression rate of ≥85%.
The passive type targets characteristic harmonics (such as the 5th/7th/11th orders generated by frequency converters) at a lower cost.
Intelligent Adaptive Control:
The active type adopts the FFT algorithm to track harmonic changes in real-time with a response time of <1ms.
Supports multi-module parallel connection to expand capacity (suitable for systems above 3000A).
Energy Efficiency Improvement:
Reduces line harmonic losses, saving 5-15% on electricity bills (depending on load conditions).
Corrects the power factor to 0.99 to avoid fines.
Reliability and Compatibility:
Complies with the strict standards of IEC 61000-3-12 and is compatible with equipment such as ABB ACS880 frequency converters.
Air-cooled design supports 7×24-hour continuous operation.
Application Fields
Industrial Frequency Conversion Systems: Compensate for harmonics in rolling mill and crane frequency converters.
Data Centers: Protect IT equipment from grid harmonic interference.
New Energy: Grid-connected filtering for photovoltaic inverters and wind power converters.
Medical Facilities: Ensure pure power supply for sensitive equipment such as MRI and CT.
Typical Scenario:
In the welding production line of an automobile factory, the PMKHRMBRC3000B eliminates voltage distortion caused by frequency converters and prevents robot malfunctions.
Installation and Maintenance
Installation: Must be operated by professional electricians to ensure the correct direction of CT.
Maintenance: Regularly clean the fan filter and check the capacitor capacity (for passive type).
