Abstract

The DC House project began in 2010 with the aim of providing alternative solutions for rural electrification, particularly in geographically difficult areas. DC House offers individuals or families, rather than community-based rural electrification. This makes the DC House solution scalable, cost-effective and flexible. It operates by running its DC load based on low-power, low-voltage DC electrical system components and systems; thus bypassing losses associated with conventional AC voltage systems. DC House also uses human power as resources to make it more sustainable in terms of power generation. This project was aimed to generate DC output voltage. The human powered swing generator first passes through the mechanical energy of the swinging motion of user. The swinging is then increasing the swing speed (rpm) by the pulley system. The increased rpm turns the DC generator clockwise and counter clockwise due to the back and forth motion of the swing. This will cause the resulting voltage to be AC, and since we want the DC output to supply DC electrical system of load, the voltage need to be convert into DC by rectifier.
