In this paper, we propose a new method of profiling the
dc-side rectifier current by using current sources placed in
parallel with each six-pulse rectifier bridge to inject current
and shape the rectifier output current. The method is simple to
implement and makes use of standard series-connected isolated
gate bipolar transistor or metal oxide semiconductor field-effect
transistor (MOSFET) modules. The property of the resulting
current sources is that they are able to deliver power to the
load, allowing for the integration of an energy storage system
on the dc side. The VA rating required to profile the current is
substantially reduced by a proper choice of the dc-side LC filter
parameters.
