DTMF BASED HOME APPLIANCE CONTROL SUBMITTED BY ABSTRACT Traditionally electrical appliances in a home are controlled via switches that regulate the electricity to these devices. As the world gets more and more technologically advanced‚ we find new technology coming in deeper and deeper into our personal lives even at home. Home automation is becoming more and more popular around the world and is becoming a common practice. The process of home automation works by making everything in the house

propose a dual-stage energy harvesting circuit composed of a seven-stage and ten-stage design‚ the former being more receptive in the low input power regions‚ while the latter is more suitable for higher power range. Each stage here is a modified voltage multiplier‚ arranged in series and our design provides guidelines on component choice and precise selection of the crossover operational point for these two stages between the high (20 dBm) and low power ( 20 dBm) extremities. Second‚ we fabricate

experiment is to test the predictions for current‚ voltage and resistance of the relationships of parallel and series circuits. The procedures strive to prove that the theoretical outcomes are consistent with the corresponding measured results. After setting up the closed circuits we want to test our own results into the equations and conclude if they are true. In the same circuit‚ there are specific equations that show how current‚ resistance and voltage behave. The equations or predictions differ

soft-switching boost converter with a magnetically coupled resonant snubber is presented in this paper. The passive snubber circuit‚ which is composed of two diodes‚ two capacitors‚ and one coupled inductor‚ ensures a zero current turn-on and zero voltage turn-off conditions for the power switch‚ and alleviates the reverse-recovery problem for the output diode. Moreover‚ with the proper design of the snubber circuit‚ the power switch and output diode can be softly switched in a wide load range. The

A. Introduction Three phase transformers are used throughout industry to change values of three-phase voltage and current. Since three-phase power is the most common way in which power is produced‚ transmitted‚ and used‚ an understanding of how three phase transformer connections are made is essential. In this section it will discuss different types of three phase transformers connections. A three-phase transformer is constructed by winding three single-phase transformers on a single core. These
