Development of a field-programmable gate array-based real-time generic solver for power electronics circuits with arbitrary configurations

Abstract

Using a field-programmable gate array (FPGA) as the core computational engine, this paper proposes a digital real-time electromagnetic transient simulator for a generic power electronic system. The LC switching model is employed for constant network conductance representation. The fully paralleled and pipelined design for network solutions and component computation accomplished the highest performance and efficiency on the FPGA. A customised 48-bit floating-point data format is proposed to achieve high simulation precision. This dedicated design is necessary for power electronic simulation. A typical power electronic transformer, which is a heavy computation burden for real-time simulation, demonstrates the effectiveness of the proposed simulator.
