Approximate Modeling of a Single‐Phase Diode Rectifier With Resistance‐Inductance Load Using the <i>g</i> ‐Function Approach

ABSTRACT This brief paper presents a compact approach for modeling currents and voltages in a single‐phase diode rectifier with a series resistance (R)–inductance (L) load. To address the nonlinear behavior during conduction intervals, approximate closed‐form solutions are derived using the g ‐function. These expressions enable fast and accurate prediction of system response without relying on numerical solvers, significantly reducing computational complexity. The proposed model is validated through simulations in MATLAB/SIMSCAPE and experimental measurements in the laboratory environment. Excellent agreement between analytical results, simulations, and experiments confirms the effectiveness and practical relevance of the proposed methodology.
