The 1140V mining intrinsically safe and Explosion Proof Drive produced by FGI adopts the IGBT clamped three-level topology. The output voltage waveform is an approximate sine wave formed by superposition, and the higher harmonic components are significantly lower than the two-level inverter`s. The interference to the power grid and control system has improved significantly. This explosion proof Variable Frequency Drive is used in coal mine scraper conveyors, high-power tape conveyor and winch control, etc.
