3-phase sinusoidal output filter for a 5.5 kW inverter SinECO-5.5/11 SINECO-5,5/11

Sine filter – protection and optimization of inverter operation

The SinECO-5.5/11 three-phase sine filter is a key element improving the power quality in systems using frequency inverters. Its task is to restore the sinusoidal voltage waveform at the output, which translates to more stable and efficient operation of connected devices. This filter is designed to work with inverters with a power of 5.5 kW, providing optimal operating parameters and minimizing potential interference.

Construction and application – for the installer and user

The filter's construction is based on CoreECO™ technology, utilizing multi-slit cores, which allows for a significant reduction in energy losses in the core and a reduction in noise and magnetizing vibrations. This translates to a longer device life and quieter system operation. The SinECO-5.5/11 filter is primarily used in motor drives powered by frequency inverters, where improving the voltage quality is crucial for reliability and efficiency. Thanks to it, the degradation of the motor and power cable insulation is limited, additional power losses are reduced, and the noise level generated by the motor is reduced.

Benefits of using a sine filter

• Motor and cable protection: Restoring the sinusoidal voltage waveform minimizes the negative impact of harmonics on the insulation of the motor and cables, extending their lifespan.
• Reduced energy losses: CoreECO™ technology lowers energy losses in the filter core, which translates to savings in electricity consumption.
• Quiet operation: The multi-slit core construction reduces noise and magnetizing vibrations, ensuring comfortable system operation.
• Improved voltage quality: The filter effectively eliminates harmonic disturbances, providing a stable power supply to connected devices.
• Compliance with standards: Using the filter helps meet the requirements of IEEE 519-1992 and PN-EN 61000-3-12 standards regarding the limitation of harmonics in the power supply network.
• Inverter optimization: The filter unloads the frequency inverter by eliminating parasitic capacitive currents.
• Customization options: It is possible to manufacture sine filters tailored to the specific needs of a given system (different switching frequencies, voltages and currents).
• Use of modern materials: The use of modern magnetic materials allows for reducing the size and weight of filters while maintaining high efficiency.
