摘要
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.
