What is a power supply circuit? A power supply basically takes the power input from a power source and converts it into a suitable current and voltage for the electrical load; hence the name “power supply,” which means supplying power to the load.However, it also has other additional benefits, such as being able to cut power in case of a short circuit, filtering out

Learn MoreThis type of linear power supply has an extremely simple circuit consisting of a transformer, bridge rectifier, and capacitors. The transformer isolates and steps down the AC voltage, the rectifier turns it into a rough DC, and the capacitors filter the DC to remove as much AC ripple as possible.
In theory, a linear battery charger with a sepa-rate power path for the system is a fairly simple design concept and can be built with an LDO adjusted to 4.2 V; a current-limit resistor; three p-channel FETs to switch the system load between the input power and the battery source; and some bias parts.
To make a linear supply with a high current output, like a box full of first-generation microprocessor and TTL chips needed, you had to use a physically large transformer. And as these were made of iron and copper, they weighed a lot.
To be precise, it is an unregulated linear power supply. Its output voltage will vary based upon the load drawn, and it will also be affected by fluctuations in the input AC line voltage. A voltage regulator is an additional electronic circuit that is connected to the output of an unregulated power supply.
We have broken linear power supplies down into four sections, as follows: Let's examine each of these sections to see what kind of components we'll be shopping for when designing a linear power supply. A transformer is an electrical device that consists of two or more coils of wire wound around a common core.
The DC produced was noisy and fluctuated at the same rate as the AC line frequency, so a large capacitor was used to smooth it out. And you now have DC power, created from AC! The system I just described is a linear power supply. To be precise, it is an unregulated linear power supply.
