This AC output filter board is a high-power module designed for ABB / Power-One Aurora photovoltaic inverters, specifically the PVI-10.0-I-OUTD and PVI-12.0-I-OUTD (isolated versions).

It is a critical component of the inverter’s AC output stage, responsible for filtering, stabilizing, and conditioning the energy before it is fed into the electrical grid.

⚙️ Main Function

The board performs the following functions:

• AC current filtering (LC filter)
• Reduction of harmonics and EMI/RFI disturbances
• Stabilization of the sinusoidal waveform
• Support of galvanic isolation (isolated “I” version)
• Protection of both the grid and the inverter

👉 Installed between the DC/AC conversion stage and the grid output

🔧 Main Components

• Power inductors (coils) for current filtering
• High-frequency magnetic element / transformer for galvanic isolation
• Aluminum heat sink for thermal management
• Industrial-grade PCB (Power-One, Pb-free)
• High-current connection terminals

⚡ Isolated “I” Version

This board is specifically designed for galvanically isolated inverters:

• Includes a high-frequency transformer (HF)
