This paper is contents that cooperationed with companies implement. Student is contents that worked as issues of ORDER-MADE-CURRICULUM. The author student teaching basic knowledge of the power supply design. We carry out analysis of factors that affect estimating the Efficiency of the electric power conversion rate characteristics of the switching power supply and efficiency and IQ(improved quality) to the factor. We used the GOGEN-SHUGI in resolve problems. The GOGEN-SHUGI is a method to identify factors from source for production processes by analyzing the actual product. We carried out improvements in function in addition using VE(Value Engineering) method. We applied functions of switching power, and fabricate reform measures and checked effect.
