TYPE-C PULSE-FORMING NETWORK COMPUTER MODEL ON THE BASIS OF IMPLICIT EULER ALGORITHM
Keywords:pulse modulator, pulse-forming network, computer simulation model, implicit Euler algorithm
This paper analyzes processes that take place in the type-C pulse-forming networks. Studying of this processes is carried out with use of computer simulation modelling. It is proposed to use implicit Euler algorithm in the pulse-forming network model design. Accordingly, computer simulation model of this pulseforming network was created. Comparative analysis of the performance of the pulse-forming network computer model based on implicit Euler algorithm with the performance of the model that was developed with use of explicit Euler algorithm was done. This analysis demonstrated that for the research object in the form of type-C pulse forming network for the chosen modelling conditions, both models exhibit almost identical precision of the pulse-forming network signals representation. This observation allowed one to make certain that the inferences concerning the correctness of the procedure of the type-C pulse-forming network synthesis made in the previous research are grounded. While studying the results of the two pulse-forming networks models trials in a greatly enlarged scale, it was established that computer simulation model based on explicit Euler algorithm does have a tendency to accumulate errors, what corroborates the inferences known from literature sources. Nevertheless, it is necessary to stress that for a small modelling increment, what is the case in the performed study, error accumulation in the computer simulation model based on the explicit Euler algorithm is insignificant. Designed computer simulation model based on implicit Euler algorithm can be used in scientific research in two major ways. The first way is in its use for other simulation models correctness verification, such as the model based on explicit Euler algorithm. Another way envisions the independent use of this model for the situations in which there is a necessity to secure minimum of errors while performing research of the pulse-forming network with help of the computer simulation modelling.
