Cascade converter

Imagine that you have a bunch of cups, and you want to fill them up with water. But, each cup is different and can only hold a certain amount of water. The first cup can hold 10 ounces, the second can hold 5 ounces, and the third can hold 3 ounces.

Now, imagine that your goal is to fill up the third cup with water, but you only have a water source that produces a steady stream of water. What do you do?

To solve this problem, you can use a cascade converter!

A cascade converter is like a series of cups, where the water flows from one cup to the next until it reaches the final cup. But, each cup has a smaller opening than the previous one, so the amount of water that can flow through decreases with each cup. This makes sure that the final cup doesn't overflow with too much water.

In our example, we can use a cascade converter by connecting the cups in a line with the biggest cup first and the smallest cup last. This means that the first cup will catch the most amount of water, but as the water flows through each cup, less and less water will be able to pass through until it reaches the third cup, which can only hold 3 ounces of water. This way, the third cup gets exactly the right amount of water it needs without overflowing.

This is similar to how a cascade converter works in electronics. It is a series of electronic components, such as diodes and capacitors, that are connected in a specific way so that the voltage or current passing through is gradually reduced to the desired level. This makes sure that the final device or component receiving the power doesn't get too much or too little power, which can cause damage.
