Board 22 - AC to DC Rectification

Board 22 – TS Troubleshooting a DC Circuit Powered by AC

Purpose: This project is used to meet the newest FAA ACS requirement to troubleshoot a DC circuit powered by an AC power supply.

Description: This project contains ten faults. The student operates the board to see how it works with a DC and AC power supplied to the transformer rectifier circuit. No output is measured from the transformer when DC is supplied. AC power can be supplied directly from a 110v outlet or by using an AC power-supply. Students can see and measure the input and output of the transformer and then a four-diode bridge rectifier circuit is used to provide the DC output. The circuit operates four LED lights.

Features

• DC and AC inputs separated by a safety supply switch.
• Troubleshooting with both an AC and DC voltmeter..
• Practical experience in identifying and tracing faults using a schematic and wiring diagram.
• Safety shield over 110-volt connections to prevent the possibility of shock.
• Comprehensive learning of a rectification circuit and LED polarity.

Includes:

• Project Booklet, Student Answer Sheet, Instructor Answer Key, Schematic Diagram, and Wiring Diagram
• Flash-drive with word document to allow diagram and direction modification by instructor
