Question

A step down chopper is operated in the continuous conduction mode in steady state with a constant duty ratio D. If $V_o$ is the magnitude of the dc output voltage and if $V_s$ is the magnitude of the dc input voltage, the ratio $V_o/V_s$ is given by

• A. $1-D$
• B. $\frac{D}{1-D}$
• C. $D$
• D. $\frac{1}{1-D}$

Answer 1

The correct option is C $D$

$V_o=D{V}_s$

$or\frac{V_o}{V_s}=D$
