design, simulate, and implement a 12W Multi Voltage AC/DCAdapter Switching Power Supply, Suitable for 3 V to 12 VDevice.
Design Specifications:
(a) Design and simulate a regulated power supply using bridgerectifier, capacitors, and Zener diode (no Integrated Circuit). Thesource voltage is 110±10 Vrms, 60 Hz  frequency.The output voltage is as follows (±5%): 3 V and7.5V
(b) The rating of the adapter will be 12W and 5% regulation. Toprotect your circuit include surge protection and fuse in thecircuit design.
(c) Total number of element should be less than 12 for reducingenvironmental impact.
(d) Total Cost of the components of your design should be lessthan $10
please do it on a breadboard as well as on the multisim. providepictures of the work done please. thank you.
