Abstract
Differently from an existing analog control, because the digital control includes microprocessor basically, the digital control is enable to monitor internal parameters of DC-DC converter and to control output voltage remotely by communicating with a Windows based PC. These things are impossible in an analog control and there are more advantages in a digital control than an analog control. In this paper, with the advantages mentioned above, the feasibility of digital controlled DC-DC converter in low price is proposed. In order to implement these functions, it is used the inexpensive H8/3672 made by Renesas that has built in AD converters and PWM logic generators. The proposed digital controller is applied to a flyback converter that is designed to output DC 5[V] from DC 20∼30[V] and is remotely controlled to make variable outputs from DC 0[V] to 5[V] above in PC. The PWM controller adopts the PD controller in PID. In the last, the response characteristics of a step reference voltage and in a steady state are experimented to verify the feasibility and the usefulness of the proposed flyback converter that is implemented inexpensively.
