This paper presents a fast response digitally controlled full bridge converter in parallel operation. The digital controlled circuit has some problem. One of the main problems is the delay time. The delay time includes the conversion time of A-D converter and processing time of digital controller. It exerts a bad influence on the dynamic characteristic. In the proposed method, the sample timing for...
The purpose of this paper is to present a new digital control switching power supply for the HVDC system in data center. The two stage converters are proposed to address the problem of input voltage drop. It consists of the boost converter and the phase-shifted full bridge converter. Since the first stage boost converter make the output voltage constant, good regulation characteristics against the...
This paper presents a novel 800W proto type digital P-I-D control switching power supply for the high voltage direct-current(HVDC) power feeding system The digital control circuit for HVDC power feeding system has some problems. Especially, the conversion time of A-D converter and the processing time of digital controller exert a bad influence upon the dynamic characteristics. In the proposed method,...
