Kertas kerja ini membentangkan peraturan dan ciri dinamik penukar dc-dc dengan kawalan PID digital, penapis FIR fasa minimum atau penapis IIR, dan kemudian kriteria reka bentuk untuk menambah baik ciri dinamik dibincangkan. Hasilnya, dijelaskan bahawa penukar DC-DC menggunakan kaedah penapis IIR mempunyai ciri prestasi yang unggul. Julat peraturan adalah dalam 1.3%, undershoot terhadap perubahan langkah beban adalah kurang daripada 2% dan masa sementara adalah kurang daripada 0.4 ms dengan kaedah penapis IIR. Dalam kes ini, frekuensi pensuisan ialah 100 kHz dan perubahan langkah beban R ialah dari 50 Ω hingga 10 Ω . Selanjutnya, ciri-ciri unggul diperoleh apabila keuntungan pertama, keuntungan kedua dan kekerapan potong kedua adalah agak besar, dan kekerapan potong pertama dan kekerapan lulus adalah agak rendah. Selain itu, adalah penting bahawa keuntungan berkurangan dengan kuat pada kekerapan potong kedua kerana julat frekuensi pas jalur atas mestilah sentiasa kurang daripada separuh daripada kekerapan pensampelan berdasarkan teori pensampelan.

Abstract: This paper presents the regulation and dynamic characteristics of the dc-dc converter with digital PID control, the minimum phase FIR filter or the IIR filter, and then the design criterion to improve the dynamic characteristics is discussed. As a result, it is clarified that the DC-DC converter using the IIR filter method has superior performance characteristics. The regulation range is within 1.3%, the undershoot against the step change of the load is less than 2% and the transient time is less than 0.4 ms with the IIR filter method. In this case, the switching frequency is 100 kHz and the step change of the load R is from 50 Ω to 10 Ω . Further, the superior characteristics are obtained when the first gain, the second gain and the second cut-off frequency are relatively large, and the first cut-off frequency and the passing frequency are relatively low. Moreover, it is important that the gain strongly decreases at the second cut-off frequency because the upper band pass frequency range must be always less than half of the sampling frequency based on the sampling theory.
