Three-phase inverter reference design for 200-480VAC drives (Rev. A) This reference design realizes a reinforced isolated three-phase inverter subsystem using isolated IGBT gate drivers and isolated current/voltage sensors.
Three-phase inverters for industrial motor drives typically employ a voltage-source inverter (VSI) configuration, consisting of six semiconductor switches (IGBTs or SiC MOSFETs) arranged in a three-arm bridge. Each arm generates a phase voltage relative to the DC bus midpoint, producing a three-phase output with 120° phase displacement.
In three-phase inverter design, control strategies are broadly categorized into open-loop and closed-loop systems. Open-loop control operates without feedback, relying solely on predefined switching patterns, while closed-loop control dynamically adjusts switching based on real-time measurements of output voltage, current, or frequency.
