Learning Optimal Synthesis of Voltage Regulators using PSPICE
Purpose - The paper aims to present a learning environment for optimal synthesis of voltage regulator circuits (LEOS-VRC) using PSPICE simulator. Design/methodology/approach - LEOS-VRC supports a database with voltage regulator circuits edited as projects in PSPICE compatible format and a methodology for optimal synthesis. The methodology is based on the estimation of multiple voltage regulator circuits' realizations over a given specification, through comparative study in PSPICE, using a set of predefined specific electrical characteristics, which values are determined from simulation waveforms. LEOS-VRC allows integrating the voltage regulator circuit in a power supply system through adding transformer, rectifier and control stages. Both linear and switch-mode power supplies are considered. Findings - The methodology and examples proposed illustrate the efficiency of LEOS-VRC for teaching and self-education in the area of power supply circuit design. Research limitations/implications - In future LEOS-VRC database will be enlarged with new voltage regulator circuit topologies and new controller circuits. Practical implications LEOS-VRC is suitable for students in electronics and designers of power supply circuits. Originality/value - With LEOS-VRC students become familiar with multisolution synthesis. By analyzing the complex behaviour of the power supply system and applying comparative study and optimization criteria, they can make a motivated selection of an optimal voltage regulator design solution for a concrete application.
