INNOVATIVE AC-DC POWER SUPPLY: A VERSATILE DUAL-MODE APPROACH TO LOCALIZED SUSTAINABLE ENERGY SOLUTION

Abstract

The developed Innovative AC-DC Power Supply Dual-Mode Distribution (ICPS-DMD) is a device created through product developmental research to provide a sustainable energy solution for local community households and schools in the mountainous Sitio Cabog in the town of Dingalan, Aurora where a university adopted school is located and recipient of the project. Two validated assessment instruments with Cronbach Alpha = 0.94 were developed and utilized. Local classroom teachers and parents of the adopted school who are residents of Sitio Cabog, assessed the ICPS-DMD for functionality, usability, and safety, while licensed electrical engineers employed in the university as experts assessed its design, materials used, and safety. Gathered data were statistically analyzed employing one-tailed t-test for independent variables, One-way ANOVA and PostHoc Analysis for Multiple Comparison using SPSS v. 20. The ICPS-DMD facilitates and controls the direct use, conversion to 220Vac and safe utilization of 12Vdc electricity supply from a car battery to provide electricity for household gadgets, appliances and instructional tools. Test results confirmed that the design and materials used to develop ICPS-DMD passed the assessment of experts with F-test = 2.233 and PostHoc analysis revealed no significant differences on the results. Said device was rated very functional, very useful, and very safe by the respondents with t-test=-1.80 in providing localized electricity supply for both 12Vdc and 220Vac powered devices for household and instructional use. Consequently, the device received patent recognition from the Intellectual Property Office of the Philippines (IPOPhil) with four sets of varying claims.
