DESIGN OF THE ZT-40 POWER CROWBAR SYSTEM

摘要

The design of a power crowbar system for 2T-40 to sustain a total current greater than 107 A with less than a 7% variation for 250 μs is discussed. The circuit performance without the power crowbar system is used to determine the power required. Several methods for supplying the power crowbar energy were investigated and simulated before choosing the final system. The advantages and disadvantages of the various options are also presented.
