摘要

Modem pulse-power generators allow obtaining multi — Mega-Ampere currents with sub-microsecond rise-times in useful loads. However, at least during a portion of the rise-time, the load inductance, Ld, can be several times smaller than that of the generator, L0, limiting the energy transfer efficiency. We define a relatively simple circuit modification, which improves the generator-to-load coupling, multiplying the load current in the case of interest, where L0>>Ld. The suggested intermediate connection operates similarly to an N:1 transformer. In its simplest configuration, for N=2, the proposed current multiplier requires an additional volume having high self-inductance, L, connected through a single convolute to both generator and load. The modified hardware allows, having possibly one additional unknown, the convolute, and without changing the current rise-time very much an increase of the load current by the factor of Id/I0=2L/(L+Ld), where Io represents the generator current and L can be easily made much greater than Ld. The benefit of the scheme usage is illustrated in simple circuit simulations for two types of potential applications with static, Ld = const, and dynamic, Ld(t), loads.
