| Abstract |
In applications where size and efficiency are
critical switched mode power supply converters are used. A
switched mode DC-DC buck converter or step-down
converter use output filter capacitor to reduce output
voltage ripple. To reduce size of buck converter, the
elimination of the capacitor must be done. Instead of the
capacitor the structure with additional linear amplifier is
introduced for output voltage ripple reduction. The
amplifier reduces ripple in output current and consequently
ripple in output voltage. The structure operation is
theoretically investigated and verified by simulations and
experimental results. |
