Questions & Step-by-Step Solutions

Which component is essential for filtering in a DC-DC converter?
  • Step 1: Understand what a DC-DC converter does. It changes one DC voltage level to another.
  • Step 2: Know that the output voltage can be unstable or have ripples.
  • Step 3: Learn that filtering is needed to make the output voltage smooth and stable.
  • Step 4: Identify that a capacitor is a component used for filtering.
  • Step 5: Recognize that the capacitor stores and releases energy to smooth out the voltage.
