A three-phase utility power supply based on the matrix converter

Abstract

A matrix converter and variable-speed diesel generator are integrated to create a three-phase utility power supply. The matrix converter is designed to meet tight harmonic and transient response requirements while allowing variable voltage and frequency input from the generator's permanent magnet alternator; This enables the generator to provide stable power over a range of engine speeds and load conditions. Test results for the 10 kW offline power supply are provided to demonstrate system performance.
