System and method for charging and discharging a superconducting coil |
摘要 |
A system and method for charging and discharging a superconducting coil (12). The system comprising a boost converter (16) coupled between a low-voltage (20) bus and a high voltage bus (18), and a buck converter coupled between the high-voltage bus and the coil. The system being configured to charge and discharge the coil without reversing the current while reversing polarity, and to only supply high-voltages when necessary. The system further comprising means (42) to dissipate excess energy during discharge. The method comprising pulse width modulating the solid-state switch of a boost converter to achieve a high-voltage from a low-voltage and then switching solid-state switches of a buck regulator to charge or discharge the coil in a non current reversing, polarity reversing manner.
