Quick and accurate response

Adopting instantaneous reactive power algorithm to improve the fast and real-time extraction of harmonic current, enhance the dynamic compensation capability of harmonic current, and quickly track the changes in harmonic current for real-time compensation when the load environment changes.

Wide filtering range

It can filter out 2-50 harmonic currents simultaneously, or select any harmonic current for compensation as needed, with high harmonic current filtering rate before and after compensation.

Comprehensive compensation function

It can achieve multifunctional compensation for harmonics, reactive power, and three-phase unbalanced currents, and can set the priority of each function according to the load environment and requirements, achieving comprehensive compensation for power quality issues.

Three level power conversion design

Adopting an advanced three-level NPC topology structure, the waveform is closer to a sine wave compared to the traditional two-level topology structure. The reverse voltage borne by the switch tube is half of the DC bus voltage, effectively increasing the switching frequency, reducing ripple current, and increasing current response speed.

Layered heat dissipation structure design

Adopting a layered heat dissipation structure design, independent air ducts are used for forced air cooling, effectively isolating the interference of dust on the control system, and facilitating centralized air cooling and heat dissipation of power switch tubes and inductors.

Modular design

Modular system, with independent operating modes, compensates for multiple harmonic currents in modules to ensure that other modules can continue to compensate when a single module is damaged. Online module replacement does not affect the control of harmonic currents, ensuring uninterrupted power quality assurance. In addition, modular design, small size, light weight, and easy installation.

Humanized interactive interface design

Adopting an industrial grade high brightness 5.7-inch touch screen with a graphical interface design and a simple, intuitive, and user-friendly design, it allows users to operate freely and monitor the operation status, compensation effect, and abnormal situations of EAPF in real time, avoiding system resonance and recording resonance conditions for better compensation.
