How does SMPS work

First of all, Alternate Current (Ac) comes to the SMPS through Power Cable which properly analyzes the components inside the SMPS like Fuse and Pf Rectifier Current and checks the voltage.

After that the current is sent to the Rectifier, the Rectifier performs operations from 120 V. to 230 V. at a time. Rectifier produces a much higher amount of DC current than AC current and this current is sent to the capacitor. All this current is in the form of small pulses, all these pulses have a lot of energy.

The Direct Current (Dc) is then checked by a regulation process and measured by a reference voltage. Which matches the power according to the design and safety requirements and to prevent any kind of disturbance and voltage failure, a controller is installed in it.
