Analysis and Implementation of Buck Boost Voltage Source Inverters Using Hybrid Electric Vehicles

This paper proposes a closed loop control an implemented to an achieve a smooth speed control irrespective of the variations in the load and input voltage fluctuations, using The space vector pulse width amplitude modulation (SVPWAM) is an efficient control technique which increases the power density and increases the efficiency. When an inverter fed with proportional and integral (PI) control technique is used for the control of dynamic load conditions, it gives a better speed and torque control. The control study analysis includes the buck boost operation of the input DC of the inverter to have a control as per the load variations, Also an attempt to reduce the THD has been made by using the closed loop control has examined by simulation/MATLAB
