Abstract

This senior project report will focus on explaining the design and operation of a variable DC wall outlet for use in the DC house. Testing will include the use of various loads using different input DC voltages not exceeding a maximum output of 90W.

The most important aspects of the outlet are to have a highly-efficient converter efficiency as well as system isolation from the main DC bus on the input. This report will outline the purpose and way of achieving isolation through use of a Flyback DC-DC converter. The user interface is the second significant aspect and details of the plug connection will be detailed along with aspects of how output voltage is selected.

Results from the finished project show that the design used does not support the load requirements on the converter. Although the variable output voltage is achieved, once the output is loaded the switches reach thermal breakdown. Recommendations for improvement of the design will be presented.
