Abstract :
A four-output leg matrix converter and a variable-speed diesel generator are integrated to create a three-phase plus neutral utility power supply. The matrix converter is designed to meet tight harmonic specification and the fourth leg provides the facility to supply unbalanced and single-phase loads. This enables the generator to provide stable power over a range of engine speeds and load conditions. Two modulation techniques for four-output leg matrix converters have been considered and compared. Test results for a 10-kW offline power supply are provided to demonstrate system performance.
