The digital controller is consisted of DSPs or microprocessors performing with software. By contrast, such as on-board SMPSs, adapting digital controller isn't still popular because of its cost or response characteristics even if the controllers are constructed by FPGA or custom LSI which is hardwarelogic base. This paper will discuss about the proposed hardware logic type digital controller for on-board SMPS, which is very simple and unique design. And, accuracy improved output voltage detection method for the proposed digital controller is proposed. The some experiments are done. And the results show the validity of the proposed circuits., 2010 IEEE Applied Power Electronics Conference and Exposition - APEC 2010 : Palm Springs, CA, USA, 2010.02.21-2010.02.25, 2010 Twenty-Fifth Annual IEEE Applied Power Electronics Conference and Exposition (APEC), pp.1879-1884}, pages = {1879--1884}, publisher = {IEEE}, title = {A design for small time-delay control circuit for DPWM- POL}, year = {2010} }
