Hi All,
I am tasked to design an AC constant current source working at 400Hz and can deliver a current upto 200mA to a transformer. The transformer is a step down (voltage) transformer which converts the current to 1A. Power Supply remains at +/-15V and load ranges from 0-2 Ohm (on the secondary side of the transformer)
I am simulating the circuit and simulation results look good. But before I build this, would like to know if having transformer as a load would place any issues with the design ?
Also all these discussions on AC current sources never talk on bandwidth. Is bandwidth not an issue at lower frequency ? Does the circuit respond to it really quickly ?
What about current regulation for varying load conditions ? Like how would the circuit respond to a 50% load regulation ?
Thanks for reading the post this far and a reply would be so appreciated
