Circuitry application:
At the output side of inverter in a synchronous motor frequency conversion transmission system, inhibits the higher harmonic current caused by the switching frequency ripple current, reduces the dv/dt transient voltage caused by traveling wave reflection in long cable transmission, so as to reduce the eddy-current losses and the noise of the electric motor, and to protect the insulation performance of the motor. Mainly used at places such as where the supply voltage is too high, modification of outdated motor, low-insulation-level non variable frequency motors, frequent braking and long cable transmissions.
