The thyristor rectifier is an established and reliable technology that has been used for decades in AC-DC conversion applications with great success. Ador Powetron provides 6 pulse, 12 pulse, 24 pulse and 48 pulse thyristor converters across the world for various application and of various ratings.
When linked to the grid, this topology frequently necessitates a more sophisticated transformer design, harmonic filters, and power factor correction (PFC) equipment. Ador offers complete power conversion solution including input transformers and rectifier cabinets, with and without PFC and Harmonic filters based on the electrolyser requirements.
