Fundamentals Of Power Supply
- Feb 07, 2018 -

We can think of a voltage-stabilized power supply as follows: When you try to get a continuous, small flow of water from a large, larger pipe, you can use two strategies: one that uses a transfer valve and opens the valve in a smaller position, which is how the linear power supply works (We can consider the valve as a transistor) the voltage regulator of the linear power supply is subjected to a great "pressure" (the specific expression is the conversion of heat to the form of dissipation).

Or, you can improve, let the water flow to a larger "bucket", the small hose is connected to the bucket to fetch water, and then all you have to do is to open/close the valve on the big water pipe intermittently, to ensure that the water in the bucket is neither completely nor because it is too much and that the basic principle of switching power supply is the same.
