Portable Nano-Hydro Power Generator For The Dc House Project, Andrew Aw, James Biggs
Portable Nano-Hydro Power Generator For The Dc House Project, Andrew Aw, James Biggs
Electrical Engineering
This senior project report explains the construction and design of a small, portable water generator that converts kinetic energy flowing in small creeks to electrical energy as a renewable source of energy for the DC House. The DC House, in short, is a project to build a self-sustainable house for Third World countries that utilizes only DC electricity. The system consists of two converters and a charge controller for a 12V lead-acid battery. The first converter converts the hydro generator voltage output to 15 Volts for safe and proper charging of the lead-acid battery by the charge controller. The second …
Bi-Directional Flyback Dc-Dc Converter For Battery System Of The Dc House Project, Austin J. Luan
Bi-Directional Flyback Dc-Dc Converter For Battery System Of The Dc House Project, Austin J. Luan
Master's Theses
The DC House project strongly relies on renewable energy sources to provide power to the house for various loads. However, when these sources are unable to provide power at a certain time, a back-up energy source from a battery must be readily available to fulfill the house’s power needs. This thesis proposes a bi-directional flyback power converter to allow a single-stage power path to charge the battery from and to discharge the battery to the DC House 48 V system bus. The design, simulation, and hardware prototype of the proposed flyback bi-directional converter will be conducted to demonstrate its feasibility. …
Multiple Input Single Output (Miso) Tablet/ Phone Charger, Kevin Wong
Multiple Input Single Output (Miso) Tablet/ Phone Charger, Kevin Wong
Master's Theses
This thesis entails the design and implementation of a multiple input single output (MISO) DC-DC converter using the flyback topology to charge tablets/ smartphones or any USB powered portable device. The MISO converter will enable the use of various renewable energy sources such as a solar panel/ rechargeable battery combination, bicycle dynamo, hydroelectric power, and wind turbine. This paper will cover the design, simulations, and test results of the MISO converter. The flyback topology was chosen due to its low part count and its efficiency at low power. The proposed converter has a nominal 12V input to output USB 2.0 …
