Electric drive |
摘要 |
An electric drive has at least one electric motor and a power converter feeding electrical motor current thereto. A current desired-value emitter generates a reference signal. An additional circuit is coupled to the current desired-value emitter so as to receive the reference signal and generates a current desired-value signal. A current regulator is coupled to the additional circuit so as to receive the current desired-value signal. The current regulator generates a control signal to the power converter so as to regulate the motor current as a function of the current desired-value signal. The additional circuit has a first mode wherein the current desired-value signal corresponds to the reference signal and a second mode wherein the current desired-value signal is a pulsed signal. |
