« Last post by Patrick66 on Today at 12:25:49 pm »Hello everyone, I'm trying to study the difference in the output response when using different compensation circuits using type 1 and type 2 compensator circuits. The question is when comparing the table of type 1 compensator test C the cross-over frequency is almost similar to the type 2 compensator test A. The problem is the overshoot and time to reach stable is much longer compared to type 2 compensators even though both have the same cross-over frequency. Wanted to ask if is this considered normal or if there is some issue with my simulation. The figures of the circuit and the table for type 1 and 2 compensator circuits is shown below. Noted that the table that has 4 different test is type 1 compensation table where as the table with 6 different test is type 2 compensation table. Thank you in advance for the help.
