Resumen del concurso

I have a DC power supply and I need to design the circuit for a display for output voltage & current in a 7-segment screen. We´ll have two screens in order to display them both at the same time.

- Voltage: 0 - 20 V +- 0.1
- Current: 0 - 1 A +- 0.01

Given the precision for both magnitudes, you'll need three digits for each display. You'll have to start the design from the analog variables. This is, you won't have to design a circuit to measure them, just take the 0-20 V and 0-1 A and need to convert that to digital and then convert to BCD for 7-segment display.

I need the file preferably for Multisim or Tina, or a schematic with the names of the components used. The components have to be taken from https://jlcpcb.com/parts and they have to have large stock.

If the design works, then you'll design the full lab power supply for 2350 USD.
