Split source inverter

A Split-Source Inverter (SSI) is a single-stage DC-AC inverter topology that combines the boosting capability

Why Use a Split-Source Inverter?

• It can boost and invert voltage in a single stage, unlike traditional two-stage systems.
• It's more compact and efficient than Z-source inverters because it uses fewer passive components.
• Especially suited for renewable energy systems, such as PV and fuel cells, where input voltage fluctuates.

🔧 Basic Circuit Description

🔹 Key Components

• 1 Inductor (L)
• 1 Capacitor (C)
• DC Source
• 3-Phase Inverter Bridge (6 switches)
• Diode (D) to direct energy flow
• Load (3-phase or resistive)

🔹 Topology

The SSI splits the source path with an inductor and capacitor in a unique configuration, allowing voltage boost capability by temporarily storing energy in the inductor and transferring it to the capacitor during switching.
