Abstract :
It is pointed out that one application of PWM (pulse width modulation) converters is in the DC transmission grid where the voltage source (boost) type converters can be connected in parallel, each converter being capable of reversing the roles of rectification/inversion on command. It is shown that the fairly large transformer leakage inductances of HVDC stations are sufficient for the proper operation of the voltage source converters. Fairly low carrier frequency can be used, assuring low switching losses.<>
