Energy feedback's research and design in AC electronic load

摘要

In modern air power ground test system, in order to accurately simulate the real load changes, we often use a type of electronic load system energy, which wastes the energy. In order to achieve power testing "green energy", we often used a grid-connected inverter in energy links of the electronic load which can make the energy back to the grid. However, due to air power supply test procedure to test the quality of demanding and test equipment can not interfere with power, So merely using the grid-connected inverter can not be a good way to achieve energy recycling. In order to solve the energy problem of waste and power grid disturbances, in this paper we propose a mixed use of super capacitors and batteries used as energy storage devices, And the two bi-directional DC / DC converter as an energy storage device controller. For this method, first we make a theoretical analysis of the feasibility and proposed method of determining the relevant parameters, finally in the PSIM simulation environment, we analysis and verify the feasibility and effectiveness of this programs.
