A. R-Dump Converter
R-dump is one of the configurations which have
one switch (lGBT) and one diode for every phase. The
value of resistance R determines the switch voltage and
also the power dissipation. To attain both realistic stress
on the switch (higher resistance R increased), and
suitable fall time of the current (lower resistance R
increased) by changing the value of resistance R. While
the T 1 switch is turned off, the current through diode D,
charging capacitor C, and afterward flows through the
external resistor R. This resistor moderately dissipatesthe energy stored in the magnetized phase [ 1 1], [ 12].
R-dump converter type is shown in Fig. 2.
