Abstract :
This paper presents the regulation and dynamic characteristics of the dc-dc converter with the digital PID control, the minimum phase FIR filter or the IIR filter. Further, we discuss the comparison of these performance characteristics. As a result, it is clarified that the variable rate of the regulation is within 1.3%, the undershoot is less than 200 mV and the transient time is less than 0.4 ms in the IIR filter method.
