A model control and a filter suppressing oscillation of the output voltage that can obtain the stable output voltage of a dc-dc converter have been proposed previous. Although there is a problem that the condition on the input side of dc-dc converter is changed when it connects the load equipment to renewable energy generators through the DC bus, since the renewable energy generators are sometimes...
We have proposed the sensorless model control based on the static model equation of the dc-dc converter that is able to change the bias value corresponding to changes of the load current, the input voltage and output voltage. The sensorless model control can regulate the output voltage. On the other hand, the transient response of output voltage is not improved. Therefore, an improvement of the transient...
Recently, the energy saving is required. It is necessary for the energy saving to operate the electric device in the sleep mode. Therefore, the output voltage rises abnormally because the dc-dc converter is required the operation in the discontinuous current mode. Therefore, we have proposed the model control using static model and strived for improvements. In the proposed method, the output voltage...
This paper presents a novel smart digital control method using P-I-D control and a model control. This control circuit is able to detect not only the average output voltage but also the input voltage and the output current to improve the dynamic characteristics. As a result, the undershoot of the output voltage, the overshoot of the reactor current and convergence time of the output voltage are improved...
In this paper, the control model for a digitally controlled DC-DC converter is presented along with derivative filter. The digital implementation of this model gives the detailed description about the gain and phase responses of each block in the digital controller loop. Key problems such as quantization resolution of digital pulse width modulator (DPWM), steady state limit cycle oscillations and...
