N2 - The paper presents a conception of power electronics voltage controlled
current source (VCCS) which is able much more precise mapping of its an
output current in a reference signal, compared to a typical converter
solution. It can be achieved by means of such interconnection of two
separate converters that one of them corrects a total output current
towards a reference signal. An output power of auxiliary converter is much
smaller than an output power of main one. Thanks to continuous work of
this converter also pulse modulation components in this current are
minimized. These benefits are paid for by a relatively small increase in
the complexity and the cost of the system. This conception of a converter
has been called the double-converter topology (DCT). In the author opinion
presented solution of the system can find application in many power
electronics equipment and, therefore, will be developed. In the paper DCT
basics, simulation experiments, and possible practical arrangement of the
DCT are presented.
