- This article proposes a quadratic boost converter that requires small components compared to the traditional quadratic boost converter. The proposed converter is based on the recently proposed Improved Super-Boost (ISB) converter, and it is driven with a particular pulse width modulation technique (PWM). This allows producing a small switching ripple (input current and output voltage) with a relatively small value of inductors and capacitors. One of the main advantages of the proposed converter is the significant voltage gain, which is equal to the traditional quadratic boost converter; the other advantage is the small size of the components. The proposed converter contains more passive components, but their size is smaller. A comparative evaluation focused on the stored energy was performed; it is demonstrated that the proposed converter requires 50% of the stored energy in inductors and 14% of the stored energy in capacitors for a particular conversion with design specifications. © IET Conference Proceedings.
