摘要：

A step-up pulse width modulation (PWM) direct current (DC)-DC converter is presented in this paper, which has its origin in quasi Z-source inverter. Analysis of this converter in steady state is presented, and relevant expressions are derived for the proposed converter operating in continuous conduction mode. The power loss expressions for each component of the converter are derived, and thereby, obtained expressions for overall converter efficiency are presented. Further, a dynamic model is derived to design an appropriate controller for this converter. The simulation and experimental results are presented to support the theoretical analysis. The advantages such as continuous input current, high step-up gain at lower duty ratio, and common ground for source, load, and switch makes the converter suitable for renewable energy applications.
