Question
**Design a +40 volt DC Power Supply for Your Sound System** Your sound system requires a 400-watt capability. The power supply is energized from a three-wire 110 V<sub>rms</sub>, 60 Hz power line that complies with the National Electric Code (NEC). Below are the system block diagram and design specifications. **Diagram Explanation:** The block diagram illustrates a basic setup for designing a power supply. It shows: - The AC input source. - A user-defined design block. - The output connected to a 400-watt audio system. - Metal box connection for safety and grounding. **Design Specifications:** - Input: 110 V<sub>rms</sub>, 60 Hz - Output voltage: 40 volts - Maximum allowable ripple: 2% - Usage of a full-wave bridge rectifier - Incorporation of a transformer - Assume diodes with V<sub>F</sub> = 0.7 volts **Your Design Must Include:** - A well-labeled circuit diagram for the design box with enough detail for creating an operational prototype. - Indicate the polarity of key components and ensure correct diode orientations. - Include key design equations and supporting calculations; show your work. **Component Specifications:** - 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. - Correctly oriented bridge rectifier, diode-current, and power ratings. - Properly located primary circuit fuse and its rating. - Correct (NEC-specified) safe wiring to the three-wire power line receptacle, including fuse location. This guide lays out the foundational structure needed for designing a robust power supply, steady enough to support a high-capacity sound system while adhering to safety and electrical standards.
