Power Quality APF/SVG

New Products / New Technology

CoEpo- APF connects to the power system in parallel, acquiring system data via external sampling. Using a core processing chip, it analyzes harmonic component data and controls high-frequency IGBT switching to generate a current that is equal in magnitude but opposite in direction to the system's harmonic currents, thereby canceling out these harmonics and mitigating their impact on the grid. CoEpo- SVG: A three-phase bridge inverter circuit is connected in parallel to the grid through an reactor. By adjusting the phase and magnitude of the AC-side output voltage of the bridge circuit, or by directly controlling its AC-side current, it provides reactive power compensation to meet system requirements.

Power Conversion System (PCS) for energy storage

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 charge and discharge operations. They are adaptable to a wide range of operating scenarios—grid‑connected, off‑grid, and seamless grid‑to‑off‑grid switching—and offer comprehensive functionality. Addressing on-site power quality challenges such as active and reactive power balance, harmonic distortion, and three‑phase load imbalance, they provide a one‑stop, integrated solution.

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.
