This paper proposes a Class D current-source resonant boost converter, which is controlled with the 1-bit delta-sigma modulator. The 1-bit delta-sigma modulator, which is an analog to digital (A/D) converter for digital audio amplifiers, generates a 1-bit (1/0) signal based on the input signal. This `periodical' output signal has an advantage in driving resonant converters. Class D voltage-source...
A novel, simple and high accuracy dual slope direct digital converter suitable for differential capacitive sensors is presented in this work. The proposed technique provides a linear digital output proportional to the parameter being sensed by differential capacitive sensors irrespective of the fact that the sensor could possess either a linear or an inverse characteristic. In the proposed technique,...
In this paper a digital control approach is investigated for time-optimal load step response of DC-DC synchronous buck converters intended for point-of-load applications employing low-ESR ceramic output capacitors. Unlike previously reported approaches, the proposed technique is insensitive to the power stage parameters, as its operation does not rely on the knowledge of the output filter inductance...
