本发明涉及一种并联逆变器系统，其中每一个逆变器中包括依次连接的同步方波发生器、电压给定发生器、电压调节单元以及功率放大单元，其特征在于，由电压调节单元所输出的电流给定不再是多选一方式，而是将所有电压调节单元中电压调节器的输出进行线性组合后再输出，把原来的不对等并联方案变为对等并联。同时，将所有同步方波发生器的输出方波进行线与后作为电压给定发生器的同步方波输入，将所有电压给定发生器输出的正弦波进行线性组合后作为电压调节单元的电压给定。 The invention relates to a parallel inverter system, in which each inverter includes a synchronized square wave generator, a voltage given generator, a voltage regulating unit and a power amplifier unit. All of them are connected in parallel in turn. The characteristic is that the output current given of the voltage regulating unit is no longer selection of one out of many any more, but outputs the output of voltage regulators of all of voltage regulating units after linear combination, thereby changing the previous unequal parallel connection to equalized parallel connection. At the same time, the output square waves of all of synchronizing square wave generators are inputted into voltage given generators as the synchronizing square wave after AND. The output sine waves of all of voltage given generators after linear combination are used as given voltage of voltage regulating units.
