摘要
电池组级联(BPCSs)电源的脉冲电容器电压是电磁推进的关键指标,重频模式下电池组多次为脉冲电容器充电后容量衰减,脉冲电容器电压在规定时间内达不到电压设定值,电磁推进的一致性将无法保证。基于BPCSs电源理论模型,提出一种时序动态调整算法,通过调整电池组串入回路的时刻来提高充电速度。实验结果表明:在电池组容量衰减40 V情况下,该算法充电时间缩短9.3%,平均电流提升10.2%,平均功率提升10.3%,能够保证重频模式下脉冲电容器电压及时达到设定值。
The pulse capacitor voltage for battery packs connected in series(BPCSs)power supply is a key metric in electromagnetic propulsion.In the repetitively charging mode,the capacity fades after the battery pack charging the pulse capacitor for many times,thus making the pulse capacitor voltage not reach the setting value of voltage in the specified time.Hence,the consistency of the electromagnetic propulsion cannot be guaranteed.A time sequence dynamic adjustment algorithm is proposed based on the theoretical model of BPCSs power supply.The time sequences are adjusted to improve the charging speed when the battery packs are connected into the circuit.The experimental results show that the charging time is shortened by 9.3%,the average current is increased by 10.2%and the average power is increased by 10.3%using the proposed method at the capacity-loss of 40 V,which makes the voltage of pulse capacitor reach the setting value in time in the repetitively charging mode.
