As a professional science and technology enterprise engaged in R&D, production, and sales of products of power electronics and power automation technology. The company focuses on smart power grid, power quality, power automation, power saving, and new energy power generation. On the aspects of energy saving and consumption reduction, improvement of power grid safety and stability, and improvement of power quality, the company independently develops multiple series products in three fields, i.e. power quality and power safety, power saving, and power automation, which have been applied to the power, industrial, petroleum and other key energy consumption fields.

Our company focuses on sales and service of Active Power Filter (APF), Static Var Generator (SVG), 3 phase load balancer, hybrid reactive power compensation cabinet. In addition to the main products, we also provide customized services such as scheme design, product customization, equipment maintenance.

YTPQC-APF Active power filters are the ultimate answer to tough power quality problems caused by harmonics, load unbalance and reactive power demand for all applications by all types of customers. They can be installed in LV networks and in MV networks through the use of a suitable coupling transformer.

Active power filter YTPQC-APF is a perfect and comprehensive solution to the power quality issues of power grid, such as harmonic wave, reactive power and three-phase load unbalance. The unit runs in parallel to the power grid, detects harmonic waves in time, generates reverse-phase compensation current through the converter and dynamically filters the harmonic waves. The operation is unaffected by multifarious load forms and power grid structures. It will not produce harmonic oscillation along with the system, thus perfectly realizing harmonic control under diverse loads.

YTPQC-APF can fully accomplish dynamic reactive compensation, control the capacitor switching and ultimately heighten the power factor of power grid. Meanwhile, it has the function of controlling the three-phase load current unbalance, thus comprehensively handling various power quality matters in power grid.

Our harmonic detection algorithm of Active Power Filter is based on ADALINE (Adaptive Linear Neuron): The error values of output compensation harmonics and load harmonics are adjusted adaptively to speed up the convergence speed and automatically adapt to different load conditions without any special control parameters setting.

YTPQC-APF active Power filters are the standard in the active filtering field for product performance. They come with:

• Unprecedented filtering efficiency with unique closed loop control system
• Stepless reactive power compensation of both inductive and capacitive loads
• Load balancing in both 3-wire and 4-wire systems
• Increasing of system reliability to unprecedented levels
• Advanced communication features with Modbus RTU and Modbus TCP
