Current-Source Inverters (also known as Sequentially Commutated Inverters) use Phase Control (as op- posed to Fast) Thyristors and Diodes. The advantages of Current Source Inverters lie in their ease control, absence of large commutation induc- tances and limited fault currents. Their simple construction, illustrated by the circuit on the left, is further enhanced by the use of MAGN-A- paks which allow the power circuit of an Inverter to be realised with 6 capacitors and 9 MAGN-A-paks all mounted on just one heatsink. The optimal design of Current Source Inverters re- quires the use of Diodes with blocking voltages greater than those of the thyristors . This departure from conventional half-bridge modules is catered for by MAGN-A-pak range with Thyristors up to 2000V and Diodes up to 3200V.
