Abstract
The parallel multiplex matrix converter couples in parallel at least two matrix converters, each of which PWM-controls bidirectional switches coupling input phases from an AC power supply to each output phases so as to output an arbitrary AC voltage or DC voltage. The output sides of the matrix converters are directly coupled in parallel to each other without any reactor. The input sides of the matrix converters use reactors inserted between the input phases from the AC power supply and the AC power supply at each of the respective matrix converters coupled in parallel.
