FPGA Based Real-Time Emulation System for Power Electronics Converters

Blog Article

This paper deals with an emulation system for Power Electronics Converters (PEC).The emulation of PECs is performed on a Field-Programmable Gate Array (FPGA) capable of hard real-time operation.To obtain such a system, the converter operation is described using a differential equations-based model designed with the Merchandise graph theory.Differential equation coefficients are changed according to the type of converter and pulse-width modulation (PWM) signals.The tie-set and incidence matrix approach for the converter modelling is performed Hemp Wicks to describe the converter operation in a general way.

Such approach enables that any type of PECs can be described appropriately.The emulator was verified experimentally by synchronous operation with a real DC-AC converter built for this purposes.
