The principle, design and implementation process of single phase electric arc furnace hardware simulation plat- form were introduced in this paper. This simulation platform consists of waveform generation circuit, power amplification circuit, simulation transformers and detection part. The operation condition of industrial electric arc furnace can be simulated by the plat-form. The waveform generation circuit can output industrial electric are furnace typical voltage waveform, which is amplified by power amplification circuit and then connected to simulation transformers to generate electric are current. The function of detec-tion part is to ensure the the electric arc voltage and current in-phase have the same phase. A new solution is adopted for hard-ware circuit design of this platform. The experimental results show that this platform can generate typical voltage waveform of electric arc furnace and corresponding current waveform, and its structure is similar with industrial electric arc furnace. An effec-tive way for electric arc furnace electrode control strategy research was provided by this platform.
