Analog Signals Conditioning and Discretization

Chapter
Part of the Power Systems book series (POWSYS)

Abstract

Chapter 2 is devoted to problems of analog signal acquisition for the digital control circuits in power electronics devices. In this chapter the problems of the measurements in power electronics circuits are highlighted. Typical systems for current and voltage measurements are discussed. Particular attention is paid to galvanic isolation and the impact of a high slew rate in common mode voltage. A discussion is presented on the selection of the sample rate and number of bits. Consideration is given to the methods and circuit design to reduce quantization noise. Included is a discussion of noise shaping circuits useful for power electronics output circuits. Also included is a section on the impact of the phenomenon of jitter on the signal to noise ratio. In this chapter a method for calculating the resultant signal to noise ratio is also shown. Finally, at the end of this chapter a presentation of selected A/D converters suitable for use in power electronics circuits is made. Special attention is paid to simultaneously sampling A/D converters.
