The objective of the present paper is to examine effects of external circuits including the Master/Slave current controller and the side-by-side power suffling circuit on the coal-fired diagonal channel, which was designed for a pilot-plant. Numerical analysis are carried out, where time-dependent 1-D gas dynamic equations are solved together with 2-D electrical equivalent circuit method. It is shown that simple current controller can be operated with much smaller electrical stress than power shuffler although the power shuffler gives better performance to a small extent. The external circuit can extend workable range of channel.
