Abstract:In this paper, a novel quadratic boost converter is proposed. The input current of the proposed converter is non-pulsating and the currents of the inductors are relatively low. The converter consists of two inductors, two capacitors, two diodes, and two power switches, where the power switches are controlled synchronously and driven by the same PWM signal. The operating principles and the mathematical model of this quadratic boost converter are presented. The steady state of the converter is analyzed and the DC values of the voltages and currents of the capacitors, inductors, power switches and diodes are concluded. Simulations and the circuit experiments are presented for confirmation.
