ABSTRACT:
In a current source power converting apparatus, in which an AC to DC converter is coupled to a DC to AC inverter through a DC reactor, two energy absorbing devices are coupled to DC terminals of the converter and the inverter, respectively, whereby there is formed a circulation circuit for circulating a current through the two energy absorbing devices and the DC reactor, when a voltage, which is higher than a predetermined value, is induced by an inductance of the DC reactor.
