Design a +40 volt de power supply for your sound system. Your sound system requires a 400 watt capability. The power supply is energized from a three-wire 110 Yens_60 Hz power line that meets the National Electric Code (NEC). The system block diagram and design specifications are given below. +40 Volts Your Design 400 Watt Audio System Metal Box Connection DESIGN SPECIFICATIONS > Input is a 110 V.ems_60 Hz Output voltage is 40 volts Maximum allowable ripple is 2% Use a full-wave bridge rectifier Use a transformer Assume diodes with Vp = 0.7 volts YOUR DESIGN MUST INCLUDE: Well-labeled circuit diagram of what goes in the "Your Design" box. There should be enough detail such that someone could build an operational_prototype. Polarities of key components as are the diode orientations are important Key design equations and supporting calculations. Show your work! Component specifications including: > Transformer-turns ratio > Effective value of the audio system load resistor (speaker impedance) and load current for a 400 watt, 40 volt system. > Capacitor value to satisfy the 2% ripple voltage specification. > Bridge rectifier, correctly oriented, with diode-current and power ratings. Correctly located primary circuit fuse and its rating. > Correct (NEC specified safe wiring) to the three wire power line receptacle. Be sure you show the fuse location.

**Designing a +40 Volt DC Power Supply for a Sound System** This guide provides the necessary steps to design a +40 volt DC power supply for a sound system with a 400-watt capability. The system is powered from a three-wire 110 V<sub>rms</sub> 60 Hz power line compliant with the National Electric Code (NEC). Below is the system block diagram and design specifications. --- **System Block Diagram:** The diagram consists of two major blocks: 1. **Your Design** - Represents the complete design of the power supply, including transformers and rectifiers. 2. **400 Watt Audio System** - Represents the sound system the power supply will power. Additionally, there is a metal box connection for grounding purposes. --- **Design Specifications:** - **Input**: 110 V<sub>rms</sub>, 60 Hz - **Output Voltage**: 40 volts - **Maximum Allowable Ripple**: 2% - **Additional Requirements**: - Use a full-wave bridge rectifier. - Use a transformer. - Assume diodes with V<sub>F</sub> = 0.7 volts. --- **Design Requirements:** Your design should include a detailed and well-labeled circuit diagram, allowing someone to construct the power supply. Pay careful attention to the polarities of key components, such as diode orientations. Ensure the circuit functions as an operational prototype. **Key Components and Considerations:** - **Transformer-turns Ratio**: Calculations to ensure the correct voltage output. - **Effective Load Resistor Value**: Accounts for speaker impedance and load current requirements. - **Capacitor Value**: Ensures the output ripple is within the 2% specification. - **Bridge Rectifier**: Correctly oriented, detailing diode current and power ratings. - **Primary Circuit Fuse**: Properly rated and located for safety. - **Wiring**: Correctly wired three-wire power line receptacle compliant with NEC standards. Clearly denote fuse location for safety. Remember to document all design equations and calculations, showing every step of your work to ensure clarity and accuracy.
