Working Principle

The TISP7290H3SL is a three-phase thyristor switch that is composed of three thyristor rectifier blocks, three bridges, three commutating stator winding outputs, a control board, and an electronic current sensor. The thyristor rectifier blocks are responsible for controlling the current in each phase. The bridges are responsible for providing isolation between the commutating stator winding power outputs and the thyristor rectifier blocks. The stator windings outputs are connected to the motor, and the electronic current sensor used to measure the current being supplied to the motor.

The control board is used to monitor and control the operation of the thyristor rectifier blocks. It is responsible for providing the appropriate gate signals to the thyristor rectifier blocks in order to control the current in each phase. The control board also contains the voltage, current and temperature sensors used by the thyristor rectifier blocks to regulate the power output of the three stator windings. Finally, the control board also monitors the power output of the stator windings and will shut down the device if it detects any anomalies.

In summary, the TISP7290H3SL is a three-step phase control thyristor switch designed to provide unmatched performance with the capability to control three-phase power in demanding high power applications.
