The paper presents analysis of problems dealing with the determination of the current setting time in the inductive component of the complex load of Voltage-to-current (VTC) converter under non-harmonic input influence. There is showed the change in the transient response and in the current setting time of the inductor on changing the VTC converter and complex load parameters. Expression to determine the current setting time of complex load of VTC converter at given level of dynamic error is presented.
In this paper, the method of determining the stability of the voltage-to-current converter (VCC) with complex load, which is built on the DC amplifier with a deep negative feedback (NFB) by current. The feedback signal is formed on precise resistor, which is connected in series with an inductive load. The deep feedback and complex load can cause a violation of the stability of the VCC across the whole dynamic range of operation.
