Question
A buck-boost DC-DC converter, shown in the figure below, is used to convert 24 V battery voltage to 36 V DC voltage to feed a load of 72 W. It is operated at 20 kHz with an inductor of 2 mH and output capacitor of 1000 µF. All devices are considered to be ideal. The peak voltage across the solid-state switch (S), in volt, is ____________.
Correct answer
59.5 to 60.5
Solution
In a buck-boost converter, the peak voltage across the switch occurs when the switch is in the OFF state. During the OFF state, the voltage across the switch is the sum of the input voltage and the output voltage .
Given:
V
VAccording to the official answer key, the acceptable range is 59.5 to 60.5.
