PSIM operates using nodal analysis and trapezoidal rule integration to provide fast and robust results. A typical project in PSIM is structured into four primary blocks:

PSIM is utilized across various industries and academic levels:

To illustrate the capabilities of PSIM, let's consider a simple example of a DC-DC converter simulation:
