This paper reports a detailed analysis of a Voltage Multiplier Coupled Quadratic Boost Converter (VM-QBC). The conventional quadratic boost converter achieves a voltage gain of $1/(1-D)^{2}$, and more voltage gain can be achieved in this converter when the duty cycle is greater than 0.7. To strengthen the numerator part of the voltage gain, a voltage multiplier cell is coupled with the quadratic boost converter, thus the VM-QBC with a gain of $2/(1-D)^{2}$ is presented in this paper. Operation of the VM-QBC is discussed in continuous conduction and discontinuous conduction modes. The voltage and current stress of various components are derived, and the components are selected. State-space model of the VM-QBC is derived, and the step response and bode plot of a significant transfer function are analyzed. The performance comparison of the VM-QBC is done with existing converters. The experimental results of a 500 W, 50 kHz, $V_{0}=350\ \mathrm{V}$ and $V_{s} =24\ \mathrm{V}$ have been observed from the laboratory setup of the VM-QBC, and the results are presented in this paper. The performance analysis of the VM-QBC and the development of its dynamic model are the significant contributions of this paper.
