The Rise of Solid-State Transformers (SSTs)

Unlike conventional transformers that rely on magnetic induction for voltage conversion, SSTs utilize power electronics to achieve the same functionality. They employ high-frequency switching devices like Insulated-Gate Bipolar Transistors (IGBTs) to convert AC to DC, perform voltage manipulation, and then convert back to AC at the desired output level.

Advantages of Solid-State Transformers

Enhanced Efficiency and Control

Solid-state transformers are known for their superior efficiency compared to traditional transformers. They minimize energy losses through advanced semiconductor components that facilitate precise control over voltage and current. This high-level control not only improves overall system efficiency but also enables dynamic response to changing load conditions, optimizing energy distribution in real time.

Compact and Environmentally Friendly

SSTs are compact and require less physical space than their oil-filled...
