دانلود Control of a Bidirectional Z-Source Inverter for Hybrid Electric Vehicles in Motoring, Regenerative Braking and Grid Interface Operations

Abstract

This paper presents a battery supplying a bidirectional Z-Source Inverter (ZSI) feeding a three phase induction motor. The indirect field-oriented control (IFOC) method is used to control the induction motor speed during motoring and regenerative braking operations. The IFOC is implemented  based  on  PWM  voltage  modulation  with  voltage  decoupling compensation. A dual loop controller is designed,  based  on  a  small  signal  model,  to  control  the  bidirectional  ZSI capacitor voltage using the bode diagram. In addition, this paper presents  the  gird  interface  mode  with  its  control  to  charge  or discharge the battery from the grid. MATLAB simulation results verified  the  validity  of  the  proposed  control  strategies  during  motoring,  regenerative  braking  and  grid  interface  operations Experimental setup of the bidirectional ZSI is under progress.
