Sine wave filter selection considerations 1. After using the sine wave filter, the load capacity of the inverter will be lower than the load capacity of the rated power frequency load of the motor. 2. The sine wave filter will cause a certain proportion of voltage drop in the filtered voltage. At a fundamental frequency of 50Hz, the voltage drop is about 10%. Its ratio is proportional to the change of the fundamental frequency. 3. The filter filters out a large number of high-order harmonic components in the process of filtering the PWM wave into a sine wave, so the inverter will have about the rated output current of the inverter when the filter is no-load. 4. After using the sine wave filter, the connectable wire length is 300m-1000m 5. For conventional sine wave filter products, the corresponding inverter output carrier frequency is 4-8KHz. If the carrier frequency of your application is not within this range, please explain to the company. Otherwise, the use of the filter will be affected, and the filter will be burned in severe cases. 6. The filter should ensure good ventilation when in use.
