Modeling of Switching Control Algorithms Over the Power Transistors of Bi-Directional Synchronous-Vector Rectifier for Storage Battery Charge

摘要

In this paper we compared the power transistor switching algorithms of electric energy converters. The algorithms of power keys switching proposed for minimizing the dimensions of filtering components and dynamic losses in switching components of a converter meeting at the same time the requirements for energy quality. We also described the circuit topology of a synchronous-vector rectifier (SVR) model. The proposed algorithms were modeled for the rectifier and inverter modes of operation using the LTSpice software circuit simulator. The obtained results are presented in the form of diagrams. The modeled algorithms provide the performance of functions of a synchronous-vector rectifier both in the rectifier and inverter modes of operation under very “modest” requirements for the parameters of filtering components.
