This paper proposes a novel A-D conversion method for the digital P-I-D control in order to improve the transient response in the switching power supply. The P-I-D control circuit has a delay time mainly due to the calculation and sampling. This delay heavily affects the transient responses. In the presented method, the P-I-D is divided into two parts, the P control and the I-D control, independently...
This paper presents a new fast response digital PID control circuit for dc-dc converter, its dynamic characteristics and the design criterion. In the conventional digital PID control method, the sampling rate is single and the calculation process of P-I-D control is series. On the other hand, in the proposed method, the sampling rate is divided each sampling period. The calculation process of P and...
This report describes the features and effectiveness of a temporary-power-supply-equipped vehicle developed for safe and efficient upgrading of power-supply equipment installed in compact stations for network access.
This paper presents transient response characteristics of digitally controlled dc-dc converter with a new control method. In the conventional digital control method, the sampling rate is single and the calculation process of P-I-D control is series. On the other hand, in the proposed method, the sampling rate is multiple and the calculation process of P and I-D controls is parallel. The AD converter...
This paper describes the optimal values of the capacitance and damping resistance of the power distribution cabinet to prevent oscillation and suppress voltage fluctuations during fuse blowing in a DC power supply system. It is useful and practical to add the capacitance and the damping resistance of the power distribution cabinet because it is easy to add them, and the system can maintain high efficiency...
