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.

Claims

1. A multiplex connection inverter apparatus having two separate inverters, which generate alternating current outputs containing carrier signal components, connected to each other for multiplexing for superposing their alternating current outputs each other, wherein

the alternating current outputs of the two inverters are superposed with their carrier signal components held opposite in the phase to each other.

2. A multiplex connection inverter apparatus according to claim 1, wherein

the alternating current outputs of the two inverters are opposite in the phase to each other while their carrier signal components are in phase with each other, and

a means is provided which has one of two output terminals thereof arranged for connecting between the positive port of one of the two inverters and the 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.

3. A multiplex connection inverter apparatus according to claim 1, wherein

the alternating current outputs of the two inverters are opposite in the phase to each other while their carrier signal components are in phase with each other, and

a means is provided for connecting between the negative ports of the two inverters and assigning the positive ports of the two inverters as the output terminals.
