Application of Learning Technology Through the Experiment of Two Fasa Inverter to Help the Human Body and Determine the Input and Output Power

Abstract

Physical experiments have a very important role in the development of science. Due to achieve that, it could be started by increasing the creativity of educators in innovating with the methods, models and learning media used. Research has been conducted with the aim of making a two phase phase inverter media to induce the human body and determine its input and output power. Method in this research was experiment. Tools and materials used include 3 Volts of inverter circuit, powerbank and finger lights. Data collection techniques by determining input and output power. Data were analyzed by using Chi-Square. The results obtained in the form of a two phase inverter experiments. Average input power (3.00 ± 0.005) Watt, output power after induction (2,250 ± 0.005) Watt and Efficiency (9.16 ± 0.005). It appeares that there is an increase in output power up to 3 times of input power. This increase in output power can be enlarged as desired by adding windings to the transformer.
