This paper will discuss about the proposed hardware logic type digital controller for on-board SMPS which has a very small time-delay in control loop. Experimental results of the load current change experiment and the frequency characteristic of open loop transfer function has been described respectively. These results reveal the validity of the proposed technique.

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.

Abstract-This paper will discuss about the proposed hard-ware logic type digital controller for on-board SMPS which has a very small time-delay in control loop. Some experimental has been done including estimation of the load current change experiment and the frequency characteristic of open loop transfer function. These result reveal the proposed circuit could be suppressed the time delay to submicrosecond order. To use the multi-phase system reduces the output ripple.
