With the current feedback module designed with IR2175, three-phase winding current can follow current reference strictly.
Decoupled control structure consisting of current feedback and voltage feed-forward is adopted in the inner current control loop which can track the reference current quickly.
At same time, the application of active current feedback data amplifier is introduced in amplifying signal of transducer.
As long as the pre-set current value and a good bonding time, the system based on current feedback signal auto - Regulation, will not be glued current thickness change and mold temperature rise.
Combined with wide band current feedback amplifier, FET input circuit and programmable circuit, variable gain amplification circuit with high speed and high input impedance is designed.
