The utility model patent discloses an Enhanced Active Power Filter with a three-phase unbalance adjustment function. The IGBT converter of the Enhanced Active Power Filter is a three-level three-phase four-wire four-arm PWM transformer. The fourth bridge arm is connected in parallel with the remaining three bridge arms, and the midpoint of the fourth bridge arm is connected to the neutra...
The existing power grid is usually equipped with a large number of nonlinear electronic components. These nonlinear electronic components will generate corresponding harmonics during the working process, among which high-order harmonics will interfere with the electrical equipment in the power grid and seriously affect the power supply. Power quality in the grid. In order to reduce the adverse eff...
Achieving capable factory functional test requires meeting multiple criteria to ensure the highest quality product. These criteria include test capability and repeatability, system upgradability and supportability, and production scalability. Setting up new production test not only involves implementing new test systems, but also managing schedule risk and budget which are often impacted by techni...

Our AHF's compensation capacity(ratio) can be set freely by the customers, to realize harmonics compensation, reactive power compensation or imbalance compensation. YT...
Power quality refers to the characteristics of electrical power, including voltage, frequency, and waveform, that affect the operation of electrical devices. Typical products for power quality improvement include: Uninterruptible Power Supply (UPS): UPS systems provide backup power during outages and voltage sags, ensuring a continuous and stable power supply to critical loads. Voltage Regulators:...
SVG and APFC are related to power factor correction in electrical systems. Here's a brief explanation of each term: SVG (Static Var Generator): SVG is a device used for dynamic reactive power compensation in electrical power systems. It is a power electronics-based device that can regulate the reactive power flow in a system to maintain a desired power factor. SVG monitors the system power factor ...
What is difference of Active Harmonic Filter and Active Power Filter? The principle of an Active Harmonic Filter AHF is to mitigate or eliminate harmonic distortion in electrical power systems. Harmonics are unwanted currents or voltages that deviate from the fundamental frequency of the power system. These harmonics are typically generated by nonlinear loads such as variable frequency drives, com...
What are the Protection function of Active Harmonic Filter? The protection functions of an Active Harmonic Filter (AHF) are critical for ensuring its safe operation, preventing damage, and maintaining the integrity of both the AHF and the electrical system it is connected to. These protection features safeguard the AHF from various electrical faults and environmental factors. Below are the key pro...
