Design Analysis of a Seven‐Level Active Neutral Point Clamped (ANPC) Inverter Based on Switched Technique

Radio Science, Volume 61, Issue 4, April 2026.
Abstract A novel switch‐based Active‐Neutral‐Clamped (ANPC) inverter for low DC‐link voltage is presented in this paper. The proposed ANPC topology minimizes switches and achieves 1.5 times better voltage gain than standard inverters. The main objective of this design is to reduce active switches in the inverter to increase system efficiency.
