摘要：A power loss analysis of multilevel current-source inverter (MCSI) circuits developed from two
basic configurations of three-level current-source inverters, i.e. H-bridge and common-emitter inverter
configurations is presented and discussed. The first circuit topology of the MCSI is developed by using DC
current modules connected to the primary three-level H-bridge inverter. The second MCSI circuit is created
by connecting the current-modules to a three-level common-emitter inverter. The DC current modules work
generating the intermediate level waveform of the inverter circuits. Power loss analysis of the both
topologies was carried out to explore the efficiency performance of the inverter circuits. The results
showed that for the H-bridge and common-emitter MCSI using DC current modules, the amount of
conduction losses in the inverter circuits could be diminished when the level number of AC output current
increase. The measurement test results have also proved that using these MCSI topologies, the power
conversion efficiency will also increase.
