Abstract

A transformerless single-phase inverter topology is proposed that can operate over a wide dc input voltage range and has the ability to track reference signals with fast dynamics, making it suitable for harmonic elimination and distributed generation applications. The necessary capacitor and inductor are easier to design than those for filtering the output of traditional inverters. Unlike traditional inverters, no output filter stage is required. Analysis of inverter operating mechanisms is carried out for two control schemes, which are confirmed by simulation and practical results.
