| Abstract |
The tandem type of ESAD is for detonating a tandem type of warhead consisting of a precursor warhead and a main warhead, ensuring safety during transport, storage, and handling of the flight vehicles. The tandem type of ESAD is armed by detecting the flight environment and is detonated in case of meeting the detonation conditions after being armed. In this case, it plays a role of detonating the precursor warhead first by outputting a detonation signal and detonating the main warhead after a certain time delay. This paper describes the design of a multi-channel high voltage generating and control circuit which is applied to a tandem type of ESAD. The tandem type of ESAD has three detonation outputs for detonating the precursor warhead and the main warhead. In particular, the detonation output for the detonation of the main warhead is designed in two channels because the concept of redundancy is needed for the stable performance and reliability of the main warhead detonation. Driving three channels of the detonating circuit for the tandem type of ESAD is implemented by designing the high voltage generating and control circuit. The proposed circuit functions to transmit a pulse and DC voltage to the inputs of the high voltage DC/DC converter. This circuit drives three DC/DC converters simultaneously, so that each detonating energy can be stably charged. |
