DETERMINISTIC AND STOCHASTIC STUDY OF THE SINGLE-PHASE NONLINEAR LOAD BEHAVIOR

摘要

The paper examines the deterministic and stochastic behavior of single-phase uncontrolled rectifiers and discharge lamps from extensive simulations performed by MATLAB customized programs. The study is based on non-linear load invariants and analyzes the harmonic current magnitudes and phase angles of these loads. Invariants are the minimum number of parameters characterizing non-linear loads univocally. Two practical laboratory examples are presented to illustrate the numerical study.
