Although the capacitive energy storage (CES) has been the dominating method so far, it has been long since people realized that inductive energy storage (IES) could be more efficient and compact [4]. The obstacle that has hampered IES has been the lack of suitable opening switches, because high-voltage, high-speed, and high-efficiency opening switch
