What resistor do I need to drop 24V to 5v?

You will require: Resistor (R1)190 Ohms – 2W or greater and (R2)50 Ohms (0.6W or greater). If you do not have the exact values stated then you will not get exactly 5 volts. Make sure that your load (what you want to use the 5v for) is a lot higher then 50 Ohms.

How can I reduce 24Vdc to 12Vdc?

We often get asked “How do you reduce 24Vdc to 12Vdc” and the answer is pretty easy – you use a DC to DC converter which has a 24Vdc (nominal) input with a regulated 12Vdc output. If you have a requirement for converting any DC voltage to any other DC voltage then please do get in touch!

Step by step method to design 5V DC power supply

  1. Step 1: The selection of regulator IC.
  2. Step 2: The selection of transformer.
  3. Step 3: The selection of diodes for the bridge.
  4. Step 4: The Selection of smoothing capacitor and calculations.
  5. Step 5: Making the power supply safe.

Why are power supply and DC-DC converter used together?

Each power supply is coupled with a DC-DC converter to keep the bus voltage constant at 650 V ( 11 ). The parallel converter architecture allows for greater flexibility in control (added degrees of freedom), T. Azib et al ( 12 ), once the final architecture is chosen and the power control supervisory logic is implemented.

What are the steps in a DC power supply?

Below is a block diagram of dc power supply in which four steps are given named as: Stepping down voltage :-First step is is scale down the voltage by a step down transformer. A step down transformer converts the 220 ac voltage to the lower ac voltage.

How to select a transformer for 5V DC power supply design?

This means we should select the transformer with a secondary voltage value equal to 9V or at least 10\% more than 9V. From these points, for the 5V DC power supply design, we can select a transformer of current rating 1A and a secondary voltage of 9V.

Which diode can be used for 5V DC output?

For 5V dc output we can use LM7805, for 9 V dc power supply we can use LM7809 and for 12V dc power supply LM7812 can be used. A diode is a device which effectively converts AC to DC.
