The control method is suitable for controlling a three-phase inverter having a plurality of switch sets, a first inductor, a second inductor, and a third inductor. The control method includes following steps: obtaining a DC bus voltage, a plurality of phase voltages, and a plurality of phase currents; obtaining inductances of the first, the second, and the third inductors; calculating a plurality of switch duty ratios by a division-summation control means according to the DC bus voltage, the phase voltages, current variations of the phase currents, the inductances, and a switching cycle based on a sinusoidal pulse width modulation (SPWM); and generating corresponding control signals based on the switch duty ratios so as to control a switching of the switch sets."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Three-phase inverting apparatus and control method and paralleled power conversion system thereof","description":"A three-phase inverting apparatus and a control method and a paralleled power conversion system thereof are provided.
