Abstract: This paper presents a simulation study of a single-phase Voltage Source Inverter (VSI), focusing on tolerance analysis at different input capacitance values. Simulations performed in MATLAB/Simulink evaluate the system behavior under current pulse injection conditions under three different capacitive configurations: 360 μF, 470 μF, and 560 μF. The transients and the degree of voltage stabilization at three nodes (Bus 1, 2, and 3) are analyzed, and a comparison is made between the amplitude ripple, overshoot, settling time, and phase symmetry.
