This paper presents a novel prediction based digital control dc-dc converter. In this method, addition to the P-I-D control as the feedback control, the prediction based control is used as the feedfoward control. In the feedfoward control, the neural network based method is adopted. This works to improve the transient response very effectively when the load is changed quickly. As a result, the undershoot...
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...
This paper presents a new digital control buck-boost dc-dc converter with bias model to improve dynamic characteristics. The buck- boost converter needs to respond appropriately to changing input voltage and load change with wide input voltage. This approach makes adjustment to the bias value by input voltage and output current. As a result, it is revealed that not only the dynamic characteristics...
The purpose of this paper is to estimate the performance characteristics of prototype of proposed digital peak current-injected control circuit using the FPGA IC. In the proposed novel digital control circuit, the peak current-injected control is realized using the combination of the simple dual A-D signal converter and the programmed delay circuit. The simple dual A-D signal converter consists of...
This paper presents the dynamic characteristics of the proposed digital control current mode dc-dc converter. In the proposed novel digital control circuit, the peak current-injected control is realized using the combination of the simple dual A-D signal converter and the programmed delay circuit. In 100 kHz digitally controlled dc-dc converter, it is seen in simulation that the proposed method has...
