SEPIC buck-boost difference

[yassin.kraouch]

Please can you give me the difference between buck-boost and sepic ??
thank you in adavance

A SEPIC is similar to a traditional buck-boost converter, but has advantages of having non-inverted output (the output voltage is of the same polarity as the input voltage) while in case of buck-boost the output voltage is of opposite polarity with respect to the input voltage.

what do you mean by inverse output ? this mean that is Vin=+Vcc ==>Vout=0V ???

 

[manishanand14]

Vout/Vin=D/[1-D]



Vout/Vin=-D/[1-D]

HI

SEPIC converter has the advantage to romove the unwanted noise through capacitor. and it give +ve output voltage. And one more advantage is it can be used as isolation dc/dc converter.

thanks

Sepic is used when the circuit needs to boost as well as buck the inout voltage but buck-oost combinedly is the inverting topology
