Abstract
In this paper, a novel quadratic boost converter is presented. The input current of the converter is non-pulsating and the currents of the inductors are relatively low. The operating principle and the mathematical model of the converter in continuous conduction mode (CCM) are given. The steady-state of the converter is calculated and the power loss of the converter is analyzed. Then the small-signal model of the converter is derived based on the state space averaging method. The inductor current and the voltage stress of the proposed converter arelow, which can improve the efficiency of the converter. The simulations and the circuit experiments are presented to verify the good performance of the converter.
