摘　　要：由于增加了液压蓄能环节,使独立稳定波浪能发电变得稳定。根据波量能发电的稳定性和蓄电池的充电特性,论述了基于DSP的全桥软开关直流变换器。该变换器主电路采用全桥零电压开关(ZVZCS)PWM拓扑结构,利用有限双极性控制,减少了开关损耗,提高了变换效率。控制电路采用模拟与数字电路相结合的控制策略,确保变换器的可靠性和灵活性。该变换器的输出稳定,功率大小可调,解决了波浪能发电与蓄电池充电特性不匹配的问题,使发电机能在最优负载状态下工作。For adds hydraulic energy-storing link before generator,the alone-stable wave device generate electricty stably.According to the dynamoelectric stabilization and the charging characteristics of batteries,a full-bridge soft-switching di-rect current converter based on DSP is discussed.The main circuit of the converter adopts full-bridge ZVZCS-PWM topolo-gy which is controlled by limited bipolar,and reduces switching losses and rises transmission efficiency.The control circuit integrates analog circuit and digital circuit,which assures the reliability and the flexibility of converter.The output of the converter is stable and the power is adjustable,which resolves the not-matching between the wave dynamoelectric charac-teristic and the charging characteristic.The converter makes the generator work in the optimal state load.
