Abstract

The paper presents a improved transformer-based full-bridge inverte. A capacitive full-bridge circuit is added to provide instant current under non-linear load condition and thereby reducing the harmonics significantly even under non-linear load condition. The redundant capacity, cost, size and weight of line frequency transformer can therefore be dramatically reduced. Moreover, a new integrated controller for inverter control is proposed to eliminate both DC current component and steady state error even under heavy load condition. The proposed integrated controller consists of a Fuzzy logic controller acts as voltage controller, DC offset canceller, an RMS compensator and non-linear load compensator. The results derived from a DSP-based inverter system and model was simulated using MATLAB/ SIMULINK software.Also the waveforms of voltage, current, harmonics, DC offset voltage are obtained.
