Joshua Dean Berk Bozoklar Experiment 2: Solid State Diodes Applications 1 January 26, 2011 The George Washington University School of Engineering and Applied Science ECE 2115 Engineering Electronics Lab Section 31 Mazdak Taghioskouei Introduction The objective of this experiment was to analyze the properties of various circuits by implementing the use of a transformer and diodes. The main circuits tested were: a half-wave rectifier, a full wave rectifier, and a bridge rectifier circuit. The DMM and Digital Oscilloscope were used in order to observe the output characteristics of the circuits. Background Information Characteristic Value + unit Convert any RMS values to V P , then V PP Primary Voltage 115Vrms V P =162.61V V PP =325.22V Frequency 60Hz Secondary Voltage 18Vrms V P = 25.452V V PP =50.904V Secondary Current Limit 1.5A n/a Calculate Power Limit (secondary V*I limit) 38.178W n/a Calculate turn ratio (N P /N S ) 6.389 n/a Table 1- Transformer Specifications

Figure 3 Full-Wave Rectifier Figure 4 Bridge-Rectifier Laboratory Experiment Section 4.2 The first part of this section required the transformer to be constructed. This was done by soldering the wires and tips together, then adding a protective insulation layer around the open wires. Next, the transformers measurements were recorded in Vrms and then converted into Vp
