| 摘 要： | 针对光伏电池本身的局限性,需要利用蓄电池来辅助对负载供电。文中所设计的双向直流变换器主要用于对蓄电池的充放电,以双向直流变换器的状态空间平均模型为基础,设计了一种新型的滑模控制器。通过实验仿真验证了基于该滑模控制器的双向直流变换器在开关管交替导通状态下能有效地减小稳态误差,且输出较稳定,能使系统具有更高的稳定性和更好的瞬时性。

| Abstract: | In terms of the limitations of photovoltaic cell itself,the battery should be needed to assist to load power supply.In this paper,a bidirectional DC/DC converter is proposed mainly for battery charging and discharging system.Then a new type of sliding model controller is designed according to the state space averaging model of bidirectional DC/DC converter.Simulation results and analysis show that the static error is effectively reduced with stable output when the proposed bidirectional DC converter is adopted for the switch tube alternate conduction,thus better system stability and transient. |
