Chapter 3 Fourier Series Representation of Period Signals

3.2 The Response of LTI Systems to Complex Exponentials It is advantageous in the study of LTI systems to represent signals as linear combinations of basic signals that possess the following two properties: • The set of basic signals can be used to construct a broad and useful class of signals.

Analog to Digital Conversion

Voltage-to-frequency converters inherently have a high noise rejection characteristic, because the input signal is effectively integrated over the counting interval. Voltage-to-frequency conversion is commonly used to convert slow and noisy signals. Voltage-to-frequency ADCs are also widely used for remote sensing in noisy environments.

The converters used are standard 7.5 kW commercial bipolar transistor PWM inverters with a rated DC-link voltage of 580V and a maximum switching frequency of 1 kHz. At this power level, the use of IGBT convert- ers would have allowed a higher switching frequency and would have eased some of the control-loop design.

Survey of Resonant Converter Topologies

converters rely on frequency modulation (FM) to achieve voltage or current regulation instead of traditional pulse width modulation (PWM). Therefore, the input-to-output voltage gain of a resonant converter can no longer be derived from the inductor volt-second balance like PWM converters and becomes much more complex than a PWM converter.

DC-DC Power Converters

120 V or 240 V ac utility voltage is rectified, producing a dc voltage of approximately 170 V or 340 V, respectively. A dc-dc converter then reduces the voltage to the regulated 5 V or 3.3 V required by the processor ICs. High efficiency is invariably required, since cooling of inefficient power converters is difficult and expensive.
