RECTIFIER (D.C. POWER SUPPLIES) - IGBT BASED RECTIFIERS
Golden Transformer & Servo's IGBT Rectifiers are meticulously crafted to fulfill the demands of industrial applications. Leveraging Insulated Gate Bipolar Transistor (IGBT) technology, these rectifiers employ high-frequency switching and pulse width modulation (PWM) techniques for precise voltage and current regulation. In contrast, silicon-controlled rectifiers (SCRs) rely on lower frequency switching and phase shift technology.
Distinguished by their compact size and reduced weight, Golden Transformer & Servo's IGBT-based Rectifiers stand out as more energy-efficient and cost-effective alternatives when compared to SCR and Rolling Contact technologies.
APPLICATION FIELD
The IGBT Rectifier finds versatile applications in various industrial processes, including Plating, Anodizing, Electro Polishing, Electrolysis, Electro Winning, Electro Refining, Cathode Electro Deposition (C.E.D. Coating), Tinning, Electronic Cleaning, Pickling, Surface Coloring, and Cathode Protection.
