TECO F510 series - 11.14 Sinusoidal output reactor

11-52
11.14 Sinusoidal output reactor
The parasitic inductance and capacitance that exist in the frequency converter and motor
wiring are determined by the component switching speed and wiring of the frequency
converter. The voltage of the motor terminal will reach as high as twice the DC voltage of
the frequency converter. LC resonance may cause surge voltages at the motor terminal
and cause danger. Installing an AC reactor at the frequency converter output can suppress
voltages (dv/dt). If the wiring length is too long, suppression of surge voltages will become
more difficult. Installing a sinusoidal output filter at the output terminal of the frequency
converter can prevent the motor terminal voltage from generating surges.
