On the issue of researching power electronics elements as the basis for constructing analog regulators

Abstract

The article discusses the issues of studying power electronics elements as the basis for the formation of analogue automatic control systems. Operational amplifiers are characterized as high-performance elements on the basis of which the basic circuits of analogue regulators (P-, I-, PI-, PD-, PID-regulators) can be built. Let us give an example of a functional diagram of a second-order linear system and its equivalent - a circuit implementation using analog elements. A diagram of the simplest version of an operational amplifier using three transistors is presented, and the concept of an amplifier stage is revealed. An example of constructing an amplifier circuit based on a bipolar transistor is considered, and the output characteristics are given.
