| Abstract | Single-phase ac/dc or dc/ac systems are inherently subject to the harmonic disturbance that is caused by the well-known double-line frequency ripple power. This issue can be eased through the installation of bulky electrolytic capacitors in the dc link. However, passive filtering approach inevitably lead to low power density and limited system lifetime. An alternative approach is to use active power decoupling so that the ripple power can be diverted into other energy storage devices to gain an improved system performance. all existing active methods have to introduce extra energy storage elements, either inductors or film capacitors in the system to store the ripple power, and this again leads to increased component costs. In the proposed project, we use a symmetrical half-bridge circuit, which uses minimum components and reduced size of the capacitors used to absorb the ripple power. Here only two capacitance of lesser value and two switches are used. The simulation is carried out with the MATLAB software and the prototype made for the same with lesser wattage for verifying the results. It shows that at least ten times capacitance reduction can be achieved with the proposed active power decoupling method. |
