Newtranstech specializes in high-power rectifier transformers seamlessly integrated with diode or thyristor rectifiers to form reliable transformer rectifier systems. These transformer rectifiers and transformer rectifier units feature highly optimized designs, making them ideal for large-scale primary aluminum electrolysis smelters as well as medium-sized industrial DC power applications.
Our regulation and rectifier transformer combinations — commonly known as rectiformers or transformer rectifier solutions — support typical 60-pulse aluminum potline configurations. They deliver excellent harmonic mitigation and superior process stability through five parallel 12-pulse rectifier groups with phase shifts of -12°, -6°, 0°, +6°, and +12°. Whether utilizing Double Star (DSS) or Double Bridge (DB) technology, our transformer rectifiers provide an ultra-wide DC voltage regulation range from 0V up to 2000V, ensuring efficient and stable DC power supply for demanding electrolytic processes.
Understanding the transformer rectifier machine definition is essential: a transformer rectifier combines voltage transformation with AC-to-DC conversion in one integrated system, unlike a standard power transformer that only steps voltage while keeping AC output. In contrast, rectifier vs transformer highlights the key difference — rectifier transformers are specially engineered to handle the non-sinusoidal currents, harmonics, and high thermal stresses associated with rectification, delivering the stable, low-ripple DC power required in heavy industrial environments.
