My needs as a potential customer: I have an amplifier system that for my purposes, needs a Power Supply to drive it. For your power supply design purposes, my amplifier system can be modelled as a simple load resistor of 2500 ohms. (i.e. the power supply output drives a load resistor of 2500 ohms).  This project can be assumed to be a competitive design process among all potential vendors

So, there are two parts to your submitted Proposal: a technical design part AND a component  cost part. I expect a complete design that meets all my technical requirements along with a parts listing and individual  parts cost for your design proposal. As part of your component costs; all components must be purchased from only USA sources and NEW but you can forget taxes and shipping costs in your cost proposal.

YOUR DESIGN TASKS:

 

  • Requirements— DESIGN a FULL WAVE BRIDGE RECTIFIER Power Supply circuit that will:
    • Take 120volts ac, 60 hz, sinusoidal waveform from the wall power and convert it to a “regulated” dc value giving 15 volts +, – 1.0 volts across a 2500 ohm output load resistor with no more than 2% ripple voltage, all at a total component parts cost of less than $175.00 (US$).

Your design process/ analysis is to be conducted by hand and by Multi-Sim of your design.

  • Consider for this design task:
    • Assume an ideal transformer and ideal diodes. As part of your design process you must consider:
  1. A filter capacitor sized per the textbook equation/Lecture material that will meet the ripple voltage requirement above. See Equations 4.28 through 4.29(b) on page 216.
  2. A turns ratio for your power transformer.
  • An ideal Zener diode within a shunt regular circuit arrangement as shown in Figure 4.21 page 205.
  1. Your design should be mindful of health and safety concerns for users and the general public with protections for its use. Describe how your design will do that. Reference link below.
  2. ALSO- I want an ON/OFF switch AND proper fusing of the power supply on input side (house power) and load side (i.e. current to the load). SO, don’t forget fusing requirements, which are:
    1. I also want fuse protection for 14 milliamps MAXIMUM going to my load resistor (AMPLIFIER INPUT RESISTANCE OF 2500 OHMS). So, add in costs for the fuses. Don’t forget the fuse holders either.
