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...
This study presents a sensorless static model based with output current estimation method for digital PWM control dc-dc converters. The static model is a feedforward type control method adopted in coordination with the standard PID control and it can improve characteristics of wide input and output range of dc-dc converter by using information of output current. The one of the drawbacks of the static...
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...
The purpose of this paper is to propose the digital control method that is comprised of the fast P control and model control for an improvement of the transient response of the dc-dc converter. The electronic devices are required the operation in the standby mode and the quick return to the active mode. The fast transient response of the dc-dc converter in such condition is important. In this paper,...
The purpose of this paper is to discuss a current prediction algorithm for sensorless model control dc-dc converter. In the proposed method, the sensing resistor for the current detection is eliminated by predicting the output current. The output current is predicted from the equation of the relationship between the output and input voltage in the static state using the duty ratio and the output voltage...
The purpose of this paper is to present a novel reference modification dc-dc converter using the reactor current sensing method and to compared its transient characteristics with the conventional output current sensing method. The proposed method uses the reactor current sensing method with the R-C filter in order to exclude the sensing resistor for the output current sensing method. Moreover, transient...
