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.

Approximate Solutions for Nonlinear Diode–RC Circuits: Short Communication Using Lambert W and g ‐Function Approaches

ABSTRACT This short communication presents approximate solutions for a nonlinear diode circuit followed by an RC shunt filter. The diode's exponential current–voltage characteristic introduces strong nonlinearity, making the analysis challenging. By applying the Lambert W function, closed‐form approximations of the circuit voltages and currents are derived. These expressions are further enhanced through a g ‐function‐based...

g‐Function‐Based Approach for Solving Nonlinear Resistor–Inductor–Diode Circuits

ABSTRACTThis brief presents a modeling approach for a nonlinear series resistor–inductor–diode (RLD) circuit powered by either a direct or alternating voltage source—a configuration commonly encountered in power electronics and energy conversion systems. Due to the diode's nonlinear current–voltage characteristic and the inductor's dynamic response, the circuit is governed by a nonlinear differential equation. Because this equation lacks a closed‐form analytical solution, a novel approximate solution...
