What Is Inverter Rear Stage Output Power? The rear stage of an inverter is responsible for converting DC (direct current) into stable AC (alternating current) with precise voltage and frequency control.
A voltage‑source inverter (VSI) has a low‑impedance DC input and synthesizes a controlled AC voltage output; it uses self‑commutating devices like MOSFETs or IGBTs.
