GYAPF Series Active Power Filter

This GYAPF Series Active Power Filter should be employed in parallel within the power grid. By detecting the load current in real time through the external CT and calculates the load current by DSP, Geyue Electric has endowed this GYAPF Series Active Power Filter with the ability to extract the harmonic components of the load. By utilizing PWM converter technology, Geyue Electric has also enabled this GYAPF Series Active Power Filter to control the IGBT, thereby allowing the internal converter device to invert a current that is of equal magnitude but opposite in direction to the harmonic current of the load and inject it into the power grid, thus achieving the function of filtering out harmonics.

1. Gain and Signal Amplification: The GYAPF Series Active Power Filter, with the invaluable assistance of active component such as an operational amplifier, has an impressive ability to provide gain. The products possesses the dual functionality of not only achieving precise filtering but also significantly amplifying signals. This attribute proves to be exceptionally useful in a wide range of application scenarios, particularly where weak and delicate signals require substantial strengthening. In contrast, the passive filters are limited in their capacity and can only result in the attenuation of signals.

2. Design Flexibility: Thanks to the elaborately developed active components by Geyue Electric, the frequency response (such as bandpass, band-stop, high-pass, low-pass, etc.) and the quality factor (Q value) of the GYAPF Series Active Power Filter can be adjusted with greater ease and flexibility. This is because the active components provide more control parameters and possibilities for manipulating the filter's characteristics. During the design process, there is no need to rely on large-volume inductors, which not only simplifies the design but also reduces the physical size and weight of the circuit. The absence of bulky inductors allows for a more compact and space-efficient circuit layout, making it suitable for applications where space is at a premium. Moreover, the use of active components enables a higher degree of customization and optimization of the filter's performance to meet specific requirements and constraints, providing engineers with more options and flexibility in the design.

3. No Load Effect: Regarding circuit characteristics, the GYAPF Series Active Power Filter made by Geyue Electric typically possesses the notable traits of high input impedance and low output impedance. This characteristic implies that in practical applications, our product is not readily influenced by the alterations in the load of the subsequent circuit. Due to this, the GYAPF Series Active Power Filter can demonstrate more stable performance. In contrast, passive filters have certain constraints. They might get detuned because of the changes in the load, thereby influencing the normal operation and performance of the entire circuit system.

4. Exceptionally Excellent Frequency Selectivity: In the practical application cases of Geyue Electric, users are always able to successfully achieve a steeper roll-off characteristic by precisely and meticulously adjusting the relevant parameters of the active components in the GYAPF Series Active Power Filter. For instance, the GYAPF Series Active Power Filter can achieve a higher-order filtering effect, thereby enabling more effective separation of the target frequency from the complex spectrum. This outstanding frequency selectivity holds significant meaning and value in many fields, such as communication and electronic engineering, and can significantly enhance the performance and working efficiency of the system.

5. Miniaturization and Low-Cost Potential: One significant advantage of Geyue Electric's GYAPF Series Active Power Filter is that it does not require large inductors. Because our GYAPF Series Active Power Filter has an outstanding ability to achieve complex functions by using smaller resistors and capacitors. This makes Geyue Electric's GYAPF Series Active Power Filter highly suitable for integrated circuit applications. The reduction in component size not only leads to a decrease in volume but also significantly reduces material costs. In the modern electronics field, the increasing demand for compact and cost-effective solutions makes this aspect extremely important. The ability to achieve the same or even better performance using smaller and cheaper components opens up new possibilities in various technical fields and enables the creation of more efficient and space-saving devices.
