Abstract:
Apparatus, systems, and methods for reducing resonance in a multiple inverter system are provided. One apparatus includes an inverter coupled to a decoupling element, wherein the inverter and the decoupling elements are couplable to a power source. A system includes a motor vehicle power source including first positive and negative terminals, and a plurality of inverters coupled to the power source. Each inverter includes a second positive terminal coupled to the first positive terminal and a second negative terminal coupled to the first negative terminal. A first inverter of the plurality of inverters includes a decoupling element coupled between the first positive terminal and the positive terminal of the first inverter. One method includes operating first and second inverters at different frequencies, and controlling the impedance of a decoupling element coupled between a power source and the first inverter based on the second inverter frequency.
