PSIM, Buck, Boost, Buck Boost, Single Phase grid tie Inverter
Abstract
The main objective of this project to reduce the Total Harmonic Distortion (THD) the transformer can be replaced by buck and boost converter there by it also increase the efficiency. This design employsa single stage switch mode buck and boost converters which has been presented for photovoltaic inverter applications. The proposed design employs a single-stage switch mode buck converter and a single-stage switch mode boost converter. So the converters are designed that the boost converter provides an output voltage of 312V DC from 24V source while the buck converter provides an output voltage of 7.07V pulsated DC from 312V AC grid. The designed buck and boost converters are then employed to run a single-phase full bridge inverter which can be simulated using the PSIM software. The results show that the designed converters can be used to replace transformers from conventional inverter circuit to make low-THD, highly efficient and cost effective transformer-lessinverter-topology
