Hello, I am trying to simulate a closed-loop Voltage Mode Control (VMC) Buck Converter. Specifically, I am comparing the performance of PSIM and QSPICE to understand how each handles the simulation of a Buck Converter.
I have designed a Type II compensator, and the voltage simulation results appear to be satisfactory. However, I am encountering issues with the frequency response. Despite multiple attempts, I have not been able to obtain a proper frequency response result.
I also modeled the system in MATLAB, where the results are as expected, so I suspect the issue lies within the simulation setup, possibly with the A-Device configuration. However, I am unsure what adjustments are needed to resolve this problem.
