STEVAL-HILE1G4K1

STEVAL-HILE1G4K1 is a HIL - hardware in the loop - cost effective emulation tool for digital power converters, based on STM32G474 and STELLAR E1 MCUs. It is designed for safe, low-voltage emulation of digital power converters, it enables verification of control algorithms by simulating a virtual power circuit where the real controller interacts under both normal and fault conditions, eliminating the risk to physical power hardware. The HIL board emulates the complete power conversion system, including AC and DC sources, converter power stages, and loads. This kit significantly reduces development time and costs by enabling early-stage testing and debugging of power converter control strategies in a risk-free environment. It supports multiple converter types such as three-phase PFC and isolated DC-DC converters, covering topologies like the Vienna rectifier, 3-Level T-type, 3-Phase 2-Level (B6), and dual active bridge (DAB) converters.

• Model-based power plant emulation
• High simulation accuracy for AFE and VSI (maximum simulation frequency: 100kHz)
• Extensive onboard I/Os: 12x PWM inputs, 20x DAC outputs
• Fault injection support: AC and DC overvoltage, AC and DC overcurrent
• User interface: pushbuttons, LEDs, potentiometers
• Grid and relay status monitoring, grid and load activation and setting
• GUI for real time monitoring and efficient debugging
