Ppt Smps Block Diagram. Here the primary power received from ac main is rectified and filtered as high voltage dc. Pwm to regulate output 9.
A smps with dc input does not require this stage. Smps block diagram 6. Hey today we are going to see and understand the smps block diagram.
The step down transformer is only a fraction of the size of a.
It is then switched at a huge rate of speed approximately 15 khz to 50 khz and fed to the primary side of the step down transformer. Smps block diagram the switched mode power supply is a dc to dc switching converter for conversion from unregulated dc input voltage to regulated dc output voltage. Here we will discuss the working principle of an smps circuit. The rectifier produces unregulated dc which is then passed through the filter circuit.
