Abstract:
A multiplex connection inverter apparatus comprising:a first inverter generating a first alternating current output that includes a first carrier signal component, a second inverter generating a second alternating current output that includes a second carrier signal component, said first and said second alternating current outputs being synchronized together to be opposite in phase while the first and second carrier signal components are in phase, and a means for generating a third alternating current output, said means having one of two output terminals thereof arranged for connecting between a positive port of one of the two inverters and a negative port of the other inverter and the other output terminal thereof arranged for connecting between the negative port of the one inverter and the positive port of the other inverter, wherein, to generate the third alternating current output, said means superposes the first and second alternating current outputs such that the superposed first and second carrier signal components are opposite in phase.
