3.3 v electronic control board design for white goods

The necessity of lower supply voltage is increasing since the electronic components are getting geometrically smaller in accordance with the developments on consumer electronics area. 3.3 V and lower operating voltages are replacing the standard 5 V designs. It has been necessary to research about advantages, disadvantages, cost, power consumption etc. in electronic control board design for white goods, since the transition period for 3.3 V supply voltage started. In this thesis, an electronic oven control board whose operating voltage is 3.3 V was designed as a prototype, and results of the process were discussed and compared to 5 V design under the headings of hardware design, power analysis and cost analysis. Additionally, the other hardware blocks (white led driver circuit, communication circuits between 5 V and 3.3 V design) that can be used in 3.3 V design were analyzed and problems that can occur in 3.3 V design and their solutions were investigated. Consequently, this thesis report which includes the details and results of the study has been presented.
