碩士 === 國立臺北科技大學 === 電機工程系研究所 === 96 === An isolated DC-AC inverter is presented herein. There are two stages in this inverter. The first stage is the DC-DC converter whereas the second stage is the DC-AC converter. Most of all, a novel cascaded pulse-width-modulated (PWM) DC-DC controller is applied to the first stage. As for the control of the second stage, a high performance digital controller named as dsPIC30F4011 is used to create the sinusoidal PWM (SPWM) control signal for the inverter so as to transfer the DC voltage to the AC voltage. In this thesis, first of all, the theoretical derivation is introduced, and secondly some simulated and experimental results are provided to verify the effectiveness of the proposed control strategy.
