Characteristics of a Developed Low-Cost Power Converter Trainer

This research assesses the characteristics of a developed Low-Cost Power Converter Trainer. Specifically, it assessed the functional analysis of the developed low-cost power converter trainer as to Cost, Appearance, Output variability, Source compatibility and Safety. Acceptability of the developed device based on TAM constructs was also evaluated. This research uses the descriptive developmental research method and utilized involving 67 respondents who were determined using the purposive sampling. The data were gathered from the respondents using a research questionnaire adopted from previous developmental studies and were analyzed using frequency count and percentage distribution and weighted mean. Result revealed that the device is perceived by the respondent’s groups as outstanding on its functionality. When categorized by occupation, the instructors and industry technicians rated all the parameter as outstanding while the OJT students in electronics perceived to be very satisfactory on item number 2 on cost. As to functionality, the three groups of respondents generally rated the device as outstanding. As to acceptability, the three groups of respondents generally rated the device as Highly Acceptable. In light of the findings of the study, the following recommendations are offered: Recommend the utilization of the output of the study in the academe, community, and industry.
