제안 방법
- To design the digital controller directly, the z-domain models of the converter were derived with consideration of the ZOH effect. By using the derived model, the digital current controller was designed with the modified K-factor approach. The advantage of the proposed method is that the bandwidth and the phase margin can be accurately designed as long as the converter is operating in physical ranges.
- Another factor is the unit sample delay caused by the iteration timing of the software routine. In this study, the software routine is iterated once in a sampling instant, and the sampling instant is synchronized to the peak or valley points of the PWM carrier. Hence, the unit sampling delay is modeled as z-1, as shown in Fig.
- By using the derived model, the digital current controller was designed with the modified K-factor approach. The advantage of the proposed method is that the bandwidth and the phase margin can be accurately designed as long as the converter is operating in physical ranges. The proposed method has been verified by simulation and experimental results from a 2.
