Control Design of a Three-phase Matrix Converter Mobile AC Power Supply using Genetic Algorithms

This paper describes the control analysis and design of a 10 kVA three-phase utility mobile power supply using matrix converters. Instead of the traditional structure employing a diode bridge rectifier, a DC link and a PWM inverter, a 3-phase to 3-phase direct AC-AC (matrix) converter has been used as the power-conditioning core of the system. An optimizing control design method, using a genetic algorithm approach, has been used which yields designs to minimize a cost function taking into account both the transient and steady state performance targets. Simulation and experimental tests have demonstrated that the system meets the requirements of the relevant international power quality standards
