Critical Study on the Relationship between Power Conversion Technique and Energy Efficiency on Set-top Box

In this paper, a critical study on the improvement of energy efficiency on the commercial set-top box along with the development of power conversion technique over the last two decades was conducted. A new classification of set-top box was proposed based on the new technologies and construction invented recently, and the past classifications of set-top box used. The corresponding energy efficiency on different types of set-top boxes was studied accordingly. A new effective labeling scheme of energy efficiency on set-top box that will be suitable in Hong Kong from 2018 to 2028 was proposed based on the recent situation and the new classification. This proposed labelling scheme can be used as reference by the manufacturers of set-top box on the selection of power conversion techniques with various levels of energy efficiency.
