Theoretical Design and Experimental Implementation of a Three-Phase Two-Level Inverter with an Adapted Gate Driver Based on Bootstrap Circuit for Grid-Connected Renewable Energy Systems

Voltage source inverters play a crucial role in connecting numerous renewable energy sources to the grid. The hardware performances and efficiency of these inverters relies on a compatible and efficient gate driver, the bootstrap circuit is a reliable technique for controlling the gates of inverter switches. Therefore, this article addresses the issue of designing and implementing a three-phase two-level voltage inverter with a gate driver based on a bootstrap circuit. However, inaccuracies in electronic components selection for the bootstrap circuit can potentially lead to a lack of compatibility between the inverter and the gate driver. Consequently, this Incompatibility may engender complications and impede the proper functioning of the inverter. This paper presents the necessary steps for implementing the inverter and the bootstrap gate driver, with a specific focus on the bootstrap circuit. The experimental results obtained from the implemented inverter validate the feasibility and functionality of the circuits. The paper provides detailed explanations of each circuit component through schematics and discusses the testing and validation processes of the implemented inverter and gate diver.
