Abstract :
In this paper, the proposed hardware logic type digital controller for on-board SMPS which has a very small time-delay in control loop has been described. Some experimental has been done including evaluation of load current change and frequency characteristic of open loop transfer function. These results have been revealed that the proposed circuit could be suppressed the time delay to sub - micro second order.
