Multiplex connection inverter apparatus
First Claim
1. 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.

Abstract
A multiplex connection inverter apparatus is provided having two separate inverters connected to each other for declining current ripples which may be generated when the superposing of the alternating current outputs with their carrier signal components held in phase with each other. The alternating current outputs of the two inverters are set opposite in the phase while their carrier signal components are in phase with each other. For connecting in parallel, the positive port of one of the two inverters is connected to the negative port of the other inverter to constitute one of two output terminals while the negative port of the one inverter is connected to the positive port of the other inverter to constitute the other output terminal. For connecting in series, the negative ports of the two inverters are connected to each other while the positive ports of the same are assigned as two output ports.
