Paper Title:
An Improved Z-Source Boost-Buck Rectifier Topology with Lower DC Output Voltage
  Abstract

A Z-source boost-buck rectifier topology has been proposed to overcome the limitation of the conventional voltage source rectifier which is a boost rectifier. Conventional Z-source rectifier topology’s lowest dc output voltage is limited because increasing the shoot-through duty ratio and the modulation index simultaneously to obtain low dc output voltage is contradictory with the principle that the sum of M and D must be lower than 1. To overcome this contradiction, this paper proposes a novel topology for Z-source rectifier which can obtain lower dc output voltage with power factor correction and less input harmonic current. This paper firstly analyzes the proposed topology and makes a comparison with the conventional one. At last, the simulation results will be presented and verify its outstanding buck capability.
