PROJECT TITLE :

Study on the Collaborative Triggering of Multiple STRETCH Meat Grinder With ICCOS Modules

ABSTRACT:

The energy density of the inductive energy storage systems is one order of magnitude higher than that of the capacitive ones. The slow transfer of energy through capacitive hybrid (STRETCH) meat grinder with inverse current commutation with semiconductor (ICCOS) devices put forward by Tsinghua University could be a typical inductive pulsed-power provide for electromagnetic launch system, which has exceptional current amplification ability as one module. But, one module cannot provide enough amplitude and width for the load current of the railgun launching. Therefore, the collaborative work of multiple inductive source modules is critical for sensible usage. In this paper, the designed inductive power offer system of concerning 1 MJ consists of 40 STRETCH meat grinders with ICCOS modules. All the main switches are opened simultaneously to reduce the magnetic field coupling among the modules and create the current rising edge steep. The modules are divided into many teams. The triggering delays of the thyristors between every 2 adjacent teams are fastidiously designed. When the first triggers for all the modules, the energy stored within the capacitors can be additional utilized with the second triggers. The numerical simulation results show that the acceptable collaborative triggering delay will increase the adjustability of the output current width and also the second triggers can more increase the present width and also the system efficiency. So, the load current with flat shape, applicable amplitude, and longer length will be given modular style and collaborate triggering discharge of the multiple modules. This could offer a theoretical foundation for the future study and implementation.
