PURPOSE: A simultaneous dual frequency inverter system is provided to improve heat treatment efficiency by being driven with dual frequency while outputting high frequency and low frequency at the same time. CONSTITUTION: In a simultaneous dual frequency inverter system, a resonant inverter system is used for a heating treatment apparatus using inductive heating A low frequency inverter outputs low frequency. A dual inverter is comprised of a high-frequency inverter(200) outputting high frequency. A primary side is respectively connected to the high frequency and low frequency inverter and receives high frequency and low frequency. The secondary side includes a CT of a dual input type outputting high frequency and low frequency. A first SDF filter removes high frequency noise. A second SDF filter removes low frequency noise.
