A sine wave filter, driven by a PWM frequency converter, provides a sine wave output voltage within a switching frequency range of 2-8kHz. In the application of frequency converter drive, this filter can eliminate the problem of motor insulation failure and reduce electromagnetic interference by eliminating high dV/dT related to the output waveform of the frequency converter, improving the performance and life of the motor, and extending the output distance of the frequency converter, up to 3km.
To protect wires and cables, using a sine wave filter can prevent overvoltage problems in long lead driven motors. In other energy applications, such as wind turbines, inverters restore electricity to practical distribution systems through step-up transformers, which can allow the use of standard transformers. If the maximum harmonic voltage distortion input to the transformer at full load and 60Hz is 5%, then the harmonic voltage distortion input to the motor at full load is generally 5%.
