How many types of power supply do you know??
Generallly, there are 4 different types of power supply to meet the needs of different networks and devices.
The first type is AC/DC power supply: this is the power supply we use for everyday devices such as cell phone chargers.
The power supply converts AC power from the grid into DC power and changes the voltage of the power to suit the needs of the devices.
The sencond type is DC/DC power supply: this is the power supply mostly used in electronics.
It modifies the voltage of the current and can change the shape of the wave if necessary.
The third type is AC/AC power supply: this is used in some very specific applications such as in some audio amplifiers.
It can lower the voltage of the network.
And the fourth type is Laboratory power supply: this can vary different current parameters to test equipment.
