dc.description.abstract | Integrated Power Systems will be used on future naval combatants. These systems will allow unprecedented control of shipboard power to propel the ship, sense the battle-space, and engage the enemy. One crucial enabling technology is robust power conversion modules like the hybrid dc to ac inverter. This thesis is a further exploration of the hybrid inverter scheme consisting of a six-step voltage-source inverter (VSI) and a hysteresis controlled current-source inverter (CSI). The six-step controller was redesigned to make it independent of the hysteresis controller. The hysteresis controller is fed a reference signal extracted from the total output current. The signal is filtered and modified by the closed-loop system such that the total output current approaches a perfect sine wave limited only by bandwidth. The modified closed-loop controller was compared to a previous Naval Postgraduate School effort and found to improve current total harmonic distortion from 3.2% to 1.8%. This thesis proves that existing power electronic technology can be used to produce high-fidelity waveforms for high-power Naval Propulsion Drives (50-100 MW). | en_US |
