◆ Product Advantages

• Integrated three-phase structure with simplified wiring: Three-phase filter capacitors are integrated into a single package to reduce connection points, lower risks of installation errors, simplify power circuit design for three-phase inverter systems and save PCB space.
• Non-inductive metallized polypropylene film structure: Non-inductive winding technology is adopted for all three-phase windings. The electrical parameters of each phase are highly consistent to guarantee balanced three-phase filtering performance.
• Excellent self-healing property: The shared metallized film dielectric for three phases features self-healing capability. Automatic recovery can be achieved upon partial breakdown of any single phase, enhancing overall system reliability.
• Compact structure and high power density: The three-phase-in-one package greatly reduces occupied volume, suitable for compact inverters with high power density requirements.

◆ Core Selling Points

• Precisely matched with three-phase Power Factor Correction (PFC): Optimized specifically for three-phase PFC circuits. It helps achieve power factor close to 1 on the three-phase power supply side and reduces reactive power loss.
• Perfectly compatible with LCL filter applications: An ideal capacitor component for three-phase LCL filter topologies, enabling grid-tied inverters to meet grid harmonic injection standards.
• High consistency and strong interchangeability: Capacitance deviation of three phases is controlled within tight tolerances with favorable batch-to-batch consistency.
• Wide voltage class coverage: Multiple AC voltage ratings are available to satisfy requirements of various inverter systems.

◆ Main Applications

• LCL filtering for three-phase grid-tied photovoltaic inverters
• AC output filtering for three-phase frequency converters
• Inverter output filtering for three-phase UPS
• Three-phase Power Factor Correction (PFC) circuits
• Three-phase Active Power Filter (APF)
