To decrease the quantization noise, various 1-bit digital filters are shown. In this paper, we propose a design method of 1-bit digital filter using an Approximate 2-Degree-of-Freedom control. The filter become very simple and the stability of the filter is easy to attain, So the dynamic range of filter is more wide than usual filters. This design method is applied to a high-pass filter, a low-pass...
Lately, it is required that the bandwidth of PWM power amplifier is extended. For example, it is in application of the testing power supply of a low frequency immunity examination, or a class-D amplifier. In this paper, we show that the bandwidth of PWM power amplifier can be extended by using an Approximate 2DOF Digital Controller. This controller is implemented on a DSP. It is demonstrated from...
To decrease the quantization noise, various 1-bit digital filters are shown. In this paper, we propose a design method of 1-bit digital filter using a new 2-degree-of-freedom control. This design method is applied to a high-pass filter, a low-pass filter and a equalizer. These filters are implemented on DSP, and the performance is verified by the experiment.
In this paper a parameter determining method of digital controller is proposed for spreading capacitance load range more and improving transient characteristics for inductance load. In the previous proposed controller, the configuration of the controller is the same to all loads. At inductive load, there is a possibility that the transient characteristics may become bad and the specification may not...
If the lines which connect the output terminal of DC-DC converter and the load are long, the voltage actually across load will be changed largely to produce the voltage drops by the impedances of the lines. Then, the terminal which senses the voltage across load is prepared apart from the output terminal of DC-DC converter, and it leads to the load, and the voltage across load is adjusted so that...

In many applications of DC-DC converters, loads cannot be specified in advance, i.e., their amplitudes are suddenly changed from the zero to the maximum rating. Generally, design conditions are changed for each load and then each controller is re-designed. Then, a so-called robust DC-DC converter which can cover such extensive load changes and also input voltage changes with one controller is needed...
