3-phase sinusoidal output filter for a 7.5 kW inverter SinECO-7.5/15 SINECO-7,5/15

Sine filter output – protection and optimization of inverter operation

The 3-phase SinECO-7.5/15 sine output filter is a key element improving the power quality in systems using frequency inverters. The device is designed to work with inverters with a power of 7.5 kW, providing harmonic reduction and restoring a sinusoidal voltage waveform at the output. This translates to a longer motor life, lower energy losses, and reduced electromagnetic interference.

Construction and application – what do you gain?

The SinECO-7.5/15 filter is designed to operate in systems powered by inverters. Its main task is to shape the output voltage waveform, close to an ideal sine wave. This reduces the degradation of motor and power cable insulation, minimizes additional power losses, and reduces the noise level generated by the motor. Additionally, the filter unloads the inverter, eliminating parasitic capacitive currents. The filter design allows for adjustment of parameters to the specific requirements of a given drive system – both in terms of switching frequency, voltage and current.

Key features and benefits

• Harmonic reduction: The filter effectively suppresses harmonics generated by the inverter, providing cleaner power to the motor.
• Motor and cable protection: By shaping the sinusoidal voltage waveform, the filter minimizes the risk of damage to motor and power cable insulation.
• Reduced energy losses: Limiting harmonics translates to lower power losses in the motor and the entire drive system.
• Quiet operation: Reducing harmonics affects the reduction of noise generated by the motor during operation.
• Inverter relief: Eliminating parasitic capacitive currents reduces the load on the inverter, which can extend its life.
• CoreECO™ technology: The use of CoreECO™ technology in the filter core allows for reducing the dimensions and weight of the device as well as reducing energy losses and magnetic vibrations.
• Compliance with standards: TRAFECO, the manufacturer of the SinECO-7.5/15 filter, has ISO 14001:2015 certification confirming care for the natural environment during production.
• Customization options: SinECO™ filters can be adapted to the individual needs of the drive system in terms of switching frequency, voltage and current (on request).
