Implementation of Parallel PSO for Synchronous Constant Current Converter

Abstract

Nowadays, the most challenging issue for power supplies designers is to build circuits capable of feeding the latest generation of microprocessors and DSP (digital signal processors), since they require a high current density while maintaining a low output voltage. A similar situation can be found when a high-power circuit is necessary to supply a continuous wave infrared laser diode array. This article follows the heuristic optimization and the design of a synchronous DC/DC (Direct Current - Direct Current) closed loop step-down converter in Matlab/Simulink having adjustable parameters for loop coefficients and reactive components, which also allows for using this converter in many other applications.
