INSTRUMENTATION AND CONTROL INTERFACES FOR ENERGY SYSTEMS AND POWER ELECTRONICS

This chapter shows that differential amplifiers are very important for distortion and noise cancellation of the electromagnetic noise induced in conductors and cables of instrumentation as common and/or differential signals, in addition to other analog circuit techniques. SimElectronics models can be used to develop control algorithms in electronic and mechatronic systems, including vehicle body electronics, aircraft servomechanisms, and audio power amplifiers. The chapter presents the most relevant aspects of basic electronic amplifiers related to applications that could affect the quality of operational amplifiers used in signal processing, electronics, and power systems in general. A data acquisition system aims at making data for automatic controls or intelligible to human decision making. The passive electrical sensors can be resistive, capacitive, or inductive. They do not require any external source of energy. PSIM allows the simulation of pulse width modulation (PWM) controllers and implementation of a sine‐wave for power converters in a very simple way.
