Switched Mode Power Supply By Kuksons Electronics Pvt. Ltd.

SMPS is basically a circuit that operates in a closed loop system to regulate the power supply output. The AC line voltage is rectified and filtered without using a line frequency isolation transformer. An optocoupler and voltage reference combination gives feedback for control purposes. Power converters may be isolated or non-isolated types.Electric power as received from the electricity supplying company is raw and comes in at 115/230 VAC 50/60 Hz. Individual domestic electrical appliances like TVs, microwave ovens, etc. operate at reduced voltage requirements. The SMPS (switching mode power supply) is a device that transforms the input voltage level to the required value. The SMPS ensures that the right amount of power is delivered to end appliances and also ensures that there is no a meltdowna with unregulated power supply.
