Step down transformer project

Project Overview In this first AC project, you will construct the simple circuit illustrated in Figure 1. Figure 1. AC step-down transformer circuit schematic diagram. This circuit uses a Parts and Materials • • • Household wall-socket power plug and cord • Line cord switch • Box (optional) • Fuse and fuse holder (optional) If you decide to equip your power supply with a fuse, be sure to get a slow-acting or slow-blow fuse. Transformers may draw high surgecurrents when initially connected to an AC source, and these transient currents will blow a fast-acting fuse.Determine the proper current rating of the fuse by dividing the transformer’s VArating by 120 V;in other words, calculate the full allowable primary winding current and size the fuse accordingly. Learning Objectives • To determine the transformer voltage step-down behavior • To determine the purpose of tapped windings • To illustrate safe wiring techniques for power cords Instructions Warning!This project involves the use of dangerous voltages. You must make sure all high-voltage (120 V household power) conductors are safely insulated from accidental contact. No bare wires should be seen anywhere on the primary (120 V)side of the transformer circuit, illustrated in Figures 1 and 2. Figure 2. AC step-down transformer circuit implementation. Step 1:Build the circuit as shown in Figures 1 and 2.Be sure to solder all wire connections so that they’re secure, and use real electrical tape (not duct tape, scotch tape, pack...
