Answer / k.prakashchandra
Switched Mode Power Supply.The working principle is
complicated. The voltage regulation is is obtained by
electronically switching elements like capacitors and
inductors off and on ,using transistors.

Answer / jigar bhatt
switched-mode power supply
SMPS converts the available unregulated ac or dc input voltage to a regulated dc output voltage. Input voltage is first rectified and filtered using a capacitor at the rectifier output. This unregulated dc voltage across the capacitor is then fed to a high frequency dc-to-dc converter. Most of the dc-to-dc converters used in SMPS circuits have an intermediate high frequency ac conversion stage to facilitate the use of a high frequency transformer for voltage scaling and isolation.
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 ‘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. The switch
employed is turned ‘ON’ and ‘OFF’ (referred as switching) at a high frequency. During ‘ON’ mode the switch is in saturation mode with negligible voltage drop across the collector and emitter terminals of the switch where as in ‘OFF’ mode the switch is in cut-off mode with negligible current through the collector and emitter terminals. On the contrary the voltage regulating switch.

SMPS - switched-mode power supply
This is used for D.C to D.C conversion.and also it will using for Ac to DC power conversion.
