Zusammenfassung:	The invention concerns a method for controlling an assembly of at least two inverters (1a, 1b) in an electricity generating system with parallel inverters. The method comprises the implementation by at least one data processing unit (2a, 2b) of the steps: (a) for each inverter (1a, 1b) of the assembly, obtaining an input duty factor (PWMi) of an input signal (Si) received by the inverter (1a,1b), (b) calculating a mean duty factor (PWMm) from the input duty factors (PWMi), (c) modulating and synchronising the input signal (Si) received by each inverter (1a, 1b) into an output signal (So) having an output duty factor (PWMo) corresponding to the mean duty factor (PWMm). 本发明涉及一种用于在具有并联逆变器的发电系统中控制至少两个逆变器(1a,1b)的组件的方法。方法包括由至少一个数据处理单元(2a,2b)实现的以下步骤：(a)对于所述组件的每个逆变器(1a,1b)，获得由逆变器(1a,1b)接收的输入信号(Si)的输入占空因数(PWMi)，(b)从输入占空因数(PWMi)计算平均占空因数(PWMm)，(c)将由每个逆变器(1a,1b)接收的输入信号(Si)调制并同步成输出信号(So)，输出信号(So)具有对应于平均占空因数(PWMm)的输出占空因数(PWMo)。
