Smps Circuit. Smps circuit is operated by switching and hence the voltages vary continuously. The high frequency transformer used in a smps circuit is much smaller in size and weight compared to the low frequency transformer of the linear power supply circuit.
The smps is mostly used where switching of voltages is not at all a problem and where efficiency of the system really matters. Using the steady state solver. If we need dc power supply for circuits we choose stepdown transformer based rectifier circuit it may give constant dc voltage under regulator ics but when the current fluctuations occurs at input power source then the dc output supply will also gets affected.
Switch mode or switching mode power supply or simply smps is a type of power supply unit psu that uses some kind of switching devices to transfer electrical energy from source to load.
The smps is mostly used where switching of voltages is not at all a problem and where efficiency of the system really matters. The switched mode power supply owes its name to the dc to dc switching converter for conversion from unregulated dc input voltage to regulated dc output voltage. This circuit can be used to power small loads or even be adapted into a charger to charge you lead acid and lithium batteries. Advantage of smps topology.
