Abstract
The paper deals with the design and realization of the power operational amplifier. Its parameters are optimized for using in four-quadrant source, especially the frequency range, slew rate, wide range of output voltage, large output current, fast current limitation and low power losses. The power operational amplifier can find utilization in the output stage of the four-quadrant power supply, low-frequency amplifiers, supply sources of servomotors etc. Whole connection is divided into single blocks and they are described in detail. The experimental results that show important static and dynamic parameters of the realized power operational amplifier are presented in the paper.
