Robust Digital Control of DC-DC Power Supply with Remote Sensing

Abstract

If the lines which connect the output terminal of a DCDC converter and the load are long, the voltage actually crossing to the load will change greatly due to the impedances of the lines, producing drops in voltage. In this paper, a separate terminal apart from the output terminal of DC-DC converter senses the voltage across to the load, and it leads it to the load. As a result, the voltage across to the load is adjusted so that it does not experience large changes. This method is called remote sensing. When the lines become long, the usual method of adjusting the voltage across to the load cannot sufficiently suppress changes in it. In this paper, a robust digital controller to suppress the change in the voltage across the load is proposed. Experimental studies using DSP demonstrate that this type of digital controller successfully suppresses it.

New Design of Socket Modules for Smart Home Applications

“…Although, there is another classification of the sockets which depends on the outlet plug used in the country, for example in USA, there are about 15 types of electrical outlet plugs existed in the market. These plugs assigned a letter by US Department of Commerce International Trade Administration (ITA), starting with A and moving through the alphabet [7]. As a fact, sockets manufactured to accept only compatible plugs inserted in the correct orientation.…”
