The high power ectifier diodes (chips' diameter up to 125mm)are processed by multi-diffusion, silicon-to-metal alloy or pressure contact, special surface passivation and cold welding encapsulation etc. Their features are high blocking voltage and also low on-state voltage, high reliability and stability, idea performance and good look.
    PERI's high power thyristors and rectifier diodes are widely used in HVDC, SVC, VVVF, PWM, high capability power supply, motor control, power switch system. They are the important basic devices for machine-electrical unification.
