A wide-band power electronics current source in reference current generator

The paper considers wide-band voltage controlled power electronics current source. The current source has been designed as a part of 1-channel reference current generator designed for current meters testing. The control module of the generator utilizes a specialized Analog Devices Inc. DSPs based microcomputer module for power electronics applications. Used solutions have allowed obtain high quality referencing of the output current within reference signal. The paper presents the structure and selected aspects of the control algorithm of the current source. Also selected investigations results of the laboratory prototype of generator are presented.
