RECTIFIER (D.C. POWER SUPPLIES) – IGBT BASED RECTIFIERS
RELIABLE’S make IGBT Rectifiers are designed to meet industrial application requirements. An insulated –Gate Bipolar Transistor (IGBT) uses relatively high frequency switching and pulse width modulation (PWM) technology for voltage and current regulation whilst a silicon controlled rectifier (SCR) uses relatively low frequency switching and phase shift technology.
“RELIABLE’S make IGBT based Rectifiers are smaller in size and lighter in weight, more energy efficient and more cost effective compared to SCR & Rolling contact type Technology”
APPLICATION FIELD
The IGBT Rectifier is used for Plating, Anodizing, Electro polishing, Electrolysis, Electro winning, Electro Refining, Cathode Electro Deposition (C.E.D. Coating), Tinning, Electronic Cleaning, Pickling, Surface Coloring, Cathode Protection.
