碩士 === 國立中興大學 === 電機工程學系所 === 101 === The thesis proposes Digitized Multi-module Power Conversion System. The three modules include a large solar-cell module, a small solar-cell module, and a battery module. This system can switch the power supply modules based on the loading for the better efficiency of power usage. Those three modules are for auxiliary power applications, the mains power supply is Utility. The large solar-cell module lowers the DC voltage using the buck converter with maximum power point tracking, and then converts DC power to AC power using a full-bridge inverter. The small solar-cell module or the other renewable power module forms an auxiliary power supply system. The battery module makes use of the car battery as the power source; its DC voltage is boosted by using a push-pull converter, and then converted to 110 VAC. A DC power monitor limits the use of the battery to ensure that the remaining voltage level is high enough to start the car’s engine when necessary. A digital signal processor (TMS320F2812) is used to realize the power management system. Availability of our design has been fully verified via real-world experiments.
