- Abstract
To solve the problem of low voltage ride through doubly-fed pumped storage motors,it adds bidirectional DC / DC and super capacitor protection branch,the bidirectional DC / DC converter adopts a two-phase interleaved bidirectional half-bridge topology. This article uses soft switching technology to effectively solve the problem of high switching loss in the converter,the soft switching technology of the converter is analyzed in Buck and Boost modes respectively. This article builds DC / DC efficiency module, transient response adjustment module, working range module and hardware circuit model in MATLAB, it adopts the control mode of double current inner loop and voltage outer loop. The simulation results show that under the action of soft switching, the switching tube realizes zero voltage turn-on and zero voltage turn-off, which effectively reduces switching losses and improves the utilization efficiency of high-power power electronic equipment. It has certain practicability and research value.
