Power Problem

Along with the development of power electronic technology, harmonic and reactive power problem for power system are increasingly serious. 3-phase Commutate System with DC/DC Converter is widely used power system, and its power factor generally very low. Circuit design can increase power factor and decrease THD for 3-phase Commutate System with DC/DC Converter , and then decrease the weight and volume . According to the simulation result ,we know that the 6kW DC/DC converter designed in this paper has lower THD , high PF . less weight , less volume and good steadiness , for example THD is less the 5%, and PF is greater than 95%.

This paper presents multifunctional operation capability of three level cascade H bridge inverter for grid connected solar pv application. The solar panel and inverter are modelled for unbalance and nonlinear loads with three control techniques (pq,dq,cpt) and its performance is simulated in the MATLAB environment using SIMULINK and Sim Power System (SPS) toolboxes. The performance of inverter is evaluated for harmonics elimination, power factor correction apart from active and reactive power support to grid and nonlinear load .Performance of three level H bridge inverter is evaluated for both PV mode and STATCOM mode using three control techniques for distribution grid.
