Half-Bridge Voltage Source Inverter Control Development Using HIL System

The paper deals with a HIL (Hardware In the Loop) system or so-called Rapid Control Prototyping (RCP) tools, used in a single-phase half-bridge Voltage Source Inverter (VSI) control development. The control algorithm is developed for the ATMEL ATmega2560 microcontroller. The code is implemented to the microcontroller via Arduino development board. A control board mock-up is assembled for control algorithm validation. HIL system is used as an RCP tool for testing. Furthermore, the VSI model is done in a HIL Schematic Editor and HIL SCADA software environment. The system functionality is tested for two selected operation points. Waveforms are recorded, and the voltage spectrum analysis is performed via external low-voltage spectrum analyzer. The shortcomings of developed system are addressed and the solution for them is proposed.
