Power Rectifiers

C&H Technology specializes in high current, high voltage industrial rectifiers with ratings from 10 to 10,000 Amps and 100 to 4,500 Volts. Applications include: welding, alternators, generators, battery chargers, electro-plating, motor drives, and traction markets.

A rectifier (or diode) is a semiconductor that has two electrodes (anode and cathode) which pass electrical current in one direction. A rectifier is used to rectify AC (alternating current) into DC (direct current). A typical semiconductor diode has a very low forward resistance (0.5 to 1.5 volts) and a reverse current of a few milliamps when blocking several hundred volts.
