D.6 Reactors
High current in the input power circuit may cause damage to the rectifying components. It is
appropriate to use AC reactor in the input side for the avoidance of high-voltage input of the
power supply and improvement of the power factors.
If the distance between the inverter and the motor is longer than 50m, frequent overcurrent
protection may occur to the inverter because of high leakage current caused by parasitic
capacitance effects from the long cables to the ground. In order to avoid the damage of the
motor insulation, it is necessary to add reactor compensation.
The inverters of 380V (≥37Kw) and of 660V are equipped with internal DC reactors for the
improvement of power factors and the avoidance of damage from high input current to the
rectifying components because of the high-capacity transformer. The device can also cease
the damage to the rectifying components which are caused by supply net voltage transients
and harmonic waves of the loads.
