This thesis proposes a complete modeling and control design methodology for a multifunctional single-phase bidirectional pwm converter in renewable energy systems. The pwm inverter system analyzed is a three phase two level voltage source inverter the inverter has been controlled using both the space vector pulse width. In this thesis, the ac small signal modeling technique is proposed for linearization of the srm model such that a conventional pi controller can be designed accordingly for the pwm current controller. This thesis discusses the advantages and drawbacks of three different pwm tech- niques: the sinusoidal pwm (spwm) technique, the third-harmonic-injection pwm (thipwm) technique, and the space-vector pwm (svpwm) technique. Pwm using matlab/simulink is the result of my own research except as cited in the references the thesis has not been accepted for any degree and is not concurrently.
