LTspice problem for stability
« on: March 24, 2024, 02:47:30 pm »
Hi! Can I know how to find my pole capacitor and zero resistor(C3, C4 and R4.) by AC open-loop. The stability : AC open-loop Bode plot has at least 45 degrees of phase margin at both 1% and 100% of the assigned Maximum Load Current.

I don't know how to get C3, C4 and R4.

Records of using the LTspice AC analysis to design the values of pole capacitors (CP3 and
CP4) and the value of zero resistor (R4) such that the AC open-loop Bode plots has at least
45 degrees of phase margin at both 1% and 100% of the assigned Maximum Load Curren.
