The ULK-THY3 System is a 3-Phase Thyristor (SCR) Rectifier designed specifically for the Power Electronics teaching environment. It provides both undergraduate and postgraduate students with a complete digitally controlled low power thyristor rectifier platform.
The system has at its core a standalone Thyristor controller that interfaces to a dedicated Thyristor (SCR) based power stage.
The thyristor controller contains all necessary digital and analog conditioned signals for operation as a controllable 3-phase rectifier.
Firing angle control is available via the front panel knobs, with an LCD to display the present operating conditions.
The ULK-THY3 controller is powered from a universal single-phase input (85 - 265VAC), which is separate to the power stage connections.
