Sinusoidal output filter:

• Output voltage in sine waves.
• Safeguard the motor cable and enable multiple motor connections.
• Use inverter and UPS AC/DC equipment to produce a sine wave and purify the equipment.
• No maximum length for the output cable.
• A type of special inverter known as a motor frequency inverter drives special frequency asynchronous motors at very near ranges (motor cable less than 100 meters).
• It typically operates in the SPWM modulation mode.
• Over 100 meters of motor cable can result in excessive du/dt, which can harm the motor's insulation, age the coils, increase core loss, and still further cause bearing heating, damage to the motor, or even burn the motor in extreme circumstances.
• To remedy this issue, the user must select a sine wave filter.
