This paper presents a digital P-I-D control switching power supply with fast proportional control. The digital control circuit has some problems. The conversion time of A-D converter and the processing time of digital controller exert a bad influence on the dynamic characteristics. In the proposed method, the calculation processes of P and I-D controls are parallel. Then the output voltage is sampled several times during one switching cycle. It is revealed that the proposed circuit has the superior transient response. Then the proposed digital control method is applied to the digitally controlled phase-shift full bridge DC-DC converter. It is confirmed that it also has the superior transient response which is verified with 800W prototype. |
