Abstract

Abstract: With the same input voltage and duty cycle, quasi-Z-source boost converter can provide higher output voltage than traditional boost converter. It has the advantages of high efficiency, wide range of practical output voltage. A quasi-Z-source boost converter topology with soft switching technology was proposed. Using assist switch replaced the diode of original topology, which could accomplish the zero voltage switching on state of the main switch. The MATLAB/Simulink simulation results show that the new topology can reduce the switch stress of main switch and increase the system stability, also it can prolong the life time of switching devices.
