BY91 Series High Quality Low Voltage Active Power/ Harmonic Filter APF 400V

Product Features of BY91 - APF - 100 - 400/4L Series APF

Modular Design:The ultra-compact design, wall-mounted and rack-mounted structures, as well as precise capacity allocation, can fully meet customer needs and are suitable for applications with limited space and renovation projects. It is easy to transport and replace and can be easily integrated into cabinets. Flexible engineering cabinet designs, plug-in cabinets, IP54 cabinets, and top and bottom cable entry designs are available to meet the diverse needs of customers.

Independent Air Duct Design:The independent air duct design adopts a circuit sealing mechanism, ensuring good heat dissipation performance and equipment safety. This structure not only facilitates installation and maintenance but also makes it easy to replace components, improving the reliability and ease of use of the system. The independent air duct design effectively prevents the intrusion of dust and impurities, extending the service life of the equipment and making it suitable for various industrial applications.

Three-level topology technology: The active power filter (APF) based on three-level topology technology has improved power quality and system efficiency. By increasing the output voltage levels, this topology makes the pulse-width modulation (PWM) waveform closer to the ideal sine wave, reducing the ripple current and harmonic content, thereby improving the harmonic compensation effect. In addition, the volume of the filter is reduced, which is conducive to modular design. The inductor loss is decreased, further enhancing the system efficiency. The voltage stress on IGBTs is halved, the switching loss is reduced, and the thermal margin is increased, enabling the system to operate stably at higher switching frequencies. Overall, the three-level topology provides a more efficient and reliable solution for modern power electronics technology.

 Introduction to Baoyu Holding Co., Ltd
Innovation drives the quality of power, and intelligent manufacturing leads the green future

Baoyu Holding Co., Ltd. is a globally leading supplier of intelligent power quality solutions. The company focuses on the research and development and production of Active Power Filters (APF), intelligent capacitors, reactors, and reactive power compensation devices, helping the industrial, new energy, and commercial sectors achieve efficient, stable, and green power management. With technological innovation at its core, through an intelligent production workshop and a digital manufacturing system, the company provides highly reliable products and services to global customers. Its business covers more than 30 countries and regions in Europe, America, Southeast Asia, the Middle East, etc.

Production Workshop: Precision Intelligent Manufacturing with a Zero-Defect Commitment
Baoyu's fully automated production workshop is constructed in line with Industry 4.0 standards, integrating cutting-edge technologies and lean management:
• Intelligent Assembly Line**: Utilizing SMT (Surface Mount Technology) assembly processes, robotic welding, and AI vision inspection, it ensures that the precision of the core components of capacitors and reactors reaches ±0.1mm, and the product consistency is ≥99.98%.
• Dynamic Aging Test: Simulating extreme environments for 72 hours (-40°C to +85°C cycles), early failure products are eliminated, and the Mean Time Between Failures (MTBF) exceeds 100,000 hours.
• Green Manufacturing: The workshop integrates a rooftop photovoltaic system, covering 30% of the energy consumption; the metal scrap recycling rate is ≥95%, achieving zero pollution emissions.

 Manufacturing Workshop: Digitally Empowered and Highly Collaborative
• MES Intelligent Management and Control: It tracks real-time data of the entire production process (yield rate, Overall Equipment Effectiveness (OEE), energy consumption), dynamically optimizing the scheduling efficiency, and shortening the order delivery cycle by 40%.
• Modular Flexible Production Line: It supports rapid switching from small-scale APFs of 50A to industrial-grade filters of 2000A, meeting customized needs.
• Clean Environment: A 10,000-class dust-free workshop is equipped with a constant temperature and humidity system (temperature ±1°C, humidity 40%-60%), ensuring zero oxidation of precision electronic components.

Core Technological Advantages
• Harmonic Governance: The APF series dynamically eliminates harmonics from the 2nd to the 50th order (THDi < 3%) and is compatible with photovoltaic inverters and Variable Frequency Drives (VFDs).
• Reactive Power Optimization: The intelligent capacitor group achieves millisecond-level switching, correcting the power factor to 0.99 and reducing line losses by 30%.
Industry Influence
Baoyu's products have been successfully applied in scenarios such as steel smelting, automobile manufacturing, data centers, and photovoltaic-wind-storage power stations. They have helped China National Offshore Oil Corporation (CNOOC) Refinery reduce electricity consumption by 25% and increase the voltage qualification rate of a Southeast Asian data center to 99.9%. With the mission of "Zero-Carbon Power, Intelligent Future Control", the company continuously promotes the efficient and low-carbon transformation of power systems.
