Other Parts Discussed in Thread: TINA-TI, , AMC1301
Tool/software: TINA-TI or Spice Models
Hello Everyone
I'm Thilesh de Silva From Sri Lanka. I simulated a part of the figure 14. DC bus Voltage sensing circuit in the Design guide of TIDA-00366 using TINA TI latest version. I have attached my simulation file to this description.
Problem is, i expected a differential output from AMC1301 but from the simulation (Steady state solver) the output of VOUTP and VOUTN is look very much similar and when the (Vdc+) - (Vdc-) Voltage is 1100 V it only gives a mV range Output as VOUTP - VOUTN. Accordin to my understanding it should be (VOUTP - VOUTN when the DC bus voltage is 1100 V) very much larger than that. Is there anything wrong in the simulation ? This is the first time i'm using TINA TI.Please explain to me. You'r valuable guidance is highly appreciated.
