Abstract
The recent advent of wide bandgap power semiconductor devices will lay the path for future power converters. These devices provide the advantage of high switching speed and lower losses. The high cost and high switching speeds of these devices provide a challenge in the development and validation of the fast-switching inverter controls with accuracy comparable to that of a hardware setup. In this paper, a field programmable gate array (FPGA) real-time simulator-based controller-hardware-in-the-loop (CHIL) testbed is used to verify the low-level and advanced inverter controls for fast-switching wide bandgap-based photovoltaic string inverter. The paper also includes development of the CHIL testbed, which is run at a time step of 500 ns in order to implement 20-kHz switching frequency. The developed CHIL testbed is validated through experimental results from a three-phase, 50-kW, 480-VLLrms SiC device-based inverter.
