摘要
Abstract—The traditional non-isolated Weinberg converter has the advantages of high power density, continuous current and easy parallel connection, which is suitable to be used as power converter and power regulator in satellite power system. This paper analyzes the working principle of traditional Weinberg converter and establishes its small signal model. Based on the traditional Weinberg converter, LC snubber circuit is added to damp the off voltage oscillation of the main switch, reduce the off loss, and offset the adverse effects of the freewheeling modes caused by the leakage inductance of the transformer and the parasitic capacitance of the main switch on the output of the topology. A detailed analysis is made on the working process of the snubber circuit, and the parameters of each part of the discharge topology are designed in detail. The discharge topology adopts the control strategy of voltage loop. Through the simulation results, the influence of the snubber circuit on the topology and the topology of the output when the load changes are analyzed. The results show that the topology design is feasible.
