POWER QUALITY APF/SVG

New Products / New Technology

"CoEpo-APF
Connected in parallel with the power system, the Active Power Filter (APF) samples real-time grid data and processes harmonic components via a core DSP controller. It drives high-frequency IGBT switches to generate equal and opposite currents, canceling out system harmonics for targeted harmonic mitigation.
CoEpo-SVG
The Static Var Generator (SVG) connects a three-phase bridge inverter to the grid in parallel through reactors. By dynamically controlling the phase, magnitude, or output current of the AC voltage, it provides real-time reactive power compensation.

ENERGY STORAGE CONVERTER (PCS)

New Products / New Technology

The CoEpo series energy storage converters (PCS) are advanced power electronic devices specifically designed for energy storage systems. Serving as a bridge for energy conversion, they enable highly efficient bidirectional conversion between direct current (DC) and alternating current (AC) during the charging and discharging of electrical energy, while also managing and controlling battery charging and discharging. The system is adaptable to various operating modes—grid‑connected, off‑grid, and seamless grid‑to‑off‑grid switching—and offers comprehensive functionality. It provides an integrated, one‑stop solution to address common power quality challenges on-site, such as active and reactive power balance, harmonic distortion, and three‑phase load imbalance.

LVR FLEXIBLE DC DISTRIBUTION AREA CAPACITY BALANCING DEVICE

New Products / New Technology

The flexible DC distribution‑area capacity‑balancing scheme applies flexible DC technology to low‑voltage distribution‑area DC power transmission. Rectifier equipment is installed at the main transformer side, while inverter equipment is installed at the secondary transformer side. The rectifier maintains stable DC voltage, and the inverter either delivers or absorbs active power, transferring excess output from the higher‑output transformer to the lower‑output one, thereby achieving balanced power delivery across the transformers.
