<p>The invention relates to a parallel inverter system, in which each inverter includes a synchronizing square wave generator, a voltage given generator, a voltage regulating unit and a power amplifier unit, all of which connected in turn. The characteristic is that the output current given of the voltage regulating unit is not the manner of selecting one from many any more, instead of which the output of voltage regulators of all of voltage regulating units are outputted after linear combination, and the scheme is the equalize parallel instead of the present unequalize parallel. At the same time output square waves of all of synchronizing square wave generators after linear and are inputted into voltage given generators as the synchronizing square wave. And output sine waves of all of voltage given generators after linear combination are given as the voltage of voltage regulating units.</p> |
