摘要
针对三端口双向DC/DC变换器在船舶电网中的应用,对其能量控制展开研究。以实现最小系统损耗为目的,对移相控制下的功率与移相比之间的关系进行分析,从而确定系统零循环功率时的移相范围,并通过解耦控制实现最小损耗。通过Matlab/Simulink仿真试验对控制策略进行验证,结果表明零循环功率控制可有效减小系统损耗。
According to the usage of three-port bidirectional DC/DC converter on the ships, the paper studies the power control. In order to achieve the minimum overall systems losses, the relation between power and phase-shift rate under phase-shifting control is analyzed. Thereby, the range of phase-shift can be calculated when the system operates at zero circulating power. The minimum losses can be achieved with the decoupled control. The control strategy is verified by simulation test with Matlab/Simulink and the results show that zero circulating power control can decrease the system losses effectively.
