This Paper focused on Buck/Boost Rectification by Single Phase Matrix Converter with fewer numbers of switches. The conventional matrix converter consists of 4 bidirectional switches, i.e. 8 set of IGBT/MOSFET with anti parallel diodes. In this proposed matrix converter, only six switches are used. The switch commutation arrangements are also carried out in this work. The gate pulses to the switches are provided by the PWM techniques. Step up or step down DC outputs can be obtained by using suitable switching algorithm. The PSIM simulation results are provided to validate the feasibility of this proposed method.

Boost Rectifier

Simulation of single phase buck boost rectifier with reduced input current THD using single phase matrix converter topology is describing in this paper. Due to the bidirectional feather the operation for buck-boost rectifier can be made through matrix converter topology. And this is possible by the proper switching algorithm to control the switches for their boost and buck operation. The input current nature is almost sinusoidal with low current total current harmonics and the level of THD is below than limit that was defined in the standards of IEEE. With the proper variation in modulation index corresponding changes in the output voltage is observed of buck-boost rectifier. For the synthesis of the output voltage Pulse width modulation (PWM) technique is used. The simulation results using MATLAB/Simulink are providing to validate the feasibility of this proposed method

Simulation Results

<p>This Work deals with design, modeling and simulation of parallel cascaded buck boost converter inverter based closed loop controlled solar system. Two buck boost converters are cascaded in parallel to reduce the ripple in DC output. The DC from the solar cell is stepped up using boost converter. The output of the boost converter is converted to 50Hz AC using single phase full bridge inverter. The simulation results of open loop and closed loop systems are compared. This paper has presented a simulink model for closed loop controlled solar system.  Parallel cascaded buck boost converter is proposed for solar system.</p>
