An inverter system is provided such that the system includes: a direct current (DC) voltage source electrically coupled with a DC link; a plurality of inverters, each of which is electrically coupled to the DC link; a plurality of motors, wherein each motor is electrically coupled with one of the inverters; and the controller is connected with each inverter. The controller may control the carrier signals of the inverters such that the carrier signals are synchronized and interleaved at an angle ([theta]) determined based on the waveform type of the carrier signals and the number of inverters in the system.
提供了一种逆变器系统,使得该系统包括:与DC链路电联接的直流(DC)电压源;多个逆变器,各个逆变器与DC链路电联接;多个电机,其中各个电机与逆变器之一电联接;以及与各个逆变器联接的控制器。控制器可以控制逆变器的载波信号,使得载波信号被同步并且以角度(θ)交错,该角度是基于载波信号的波形类型和系统中的逆变器的数量确定的。
