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 Vrms 60 Hz power line that meets the National Electric Code (NEC). The system block diagram and design specifications are given below. Input is a 110 Vrms60 Hz. Output voltage is 40 volts, unregulated. Maximum allowable ripple is 2% Use a full-wave bridge rectifier. Use a transformer Assume diodes with VF= 0.7 volts Your design should include: Ø 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 are important Ø Key design equations and supporting calculations. Show your work! Ø Component specifications including: (a) Transformer-turns ratio (b) Effective value of the audio system load resistor (speaker impedance) and load current for a 400 watt, 40 volt system. (c) Capacitor value to satisfy the 2% ripple voltage specification. (d) Bridge rectifier diode-current and power ratings. (e) Correctly located primary circuit fuse and its rating. (f) Correct (NEC specified safe wiring) to the three wire power line receptacle.
