Advantages
-
Utilizes a three-level structure (topology), reducing the voltage stress on individual IGBTs and lowering du/dt.
-
Employs an LCL filter circuit. The LCL filter circuit can effectively absorb high-frequency harmonics.
-
Fast response speed, with a full response time of approximately 3.8ms.
-
The hardware platform is built using components from internationally renowned manufacturers, effectively ensuring product quality.
-
High-precision analog sampling design.
