Block Diagram And Working Of Smps. In a dc to dc converter primarily a high voltage dc power is directly obtained from a dc power source. Block diagram and working of smps the major components that constitute smps are as follows.
212 linear regulated power supply fig. Block diagram and working of smps the major components that constitute smps are as follows. Smps stands for switch mode power supply.
301 shows a block diagram example of a typical smps with an ac mains line input and a regulated dc output.
Generally transistors mosfet are used as regulating switching device whose input is a train of pulses. Draw and explain the block diagram of smps. Todays modern computers have an smps that takes the improved ac input power from the board in the house by making a power factor correction and then converting the output to a single or lower voltage dc output. The output rectification and filter are isolated from the high frequency switching section by a high frequency transformer and voltage control feedback is via an opto isolator.
