Abstract
Operating several power electronics modules in parallel can have
distinct advantages compared to a system which consists of only
one module for the same total power rating. Some of these
advantages are:
— higher effective inverter frequency
— inherent redundancy
— lower distortion of input and output waveforms.
These advantages can only be realized in practice when a control
system takes care of the correct phase—shifting over 360/n
degrees of the pulse pattern of the individual modules. A control
method is presented whose philosophy allows any number of power
modules to be operated in this manner, even under transient
conditions
