The 5SGY3545L0017 thyristor active rectifier is a semiconductor electronic device consisting of at least three PN junctions (i.e. a combination of P-type semiconductors and N-type semiconductors). It has unidirectional conductivity and controllable turn-off characteristics, and can convert AC voltage to DC voltage. The rectifier has many advantages such as high efficiency, no mechanical noise and wear, fast response speed, small size and light weight.

Second, the working principle

The working principle of the 5SGY3545L0017 thyristor rectifier is based on the characteristics of the thyristor. In the forward blocking state, if a low-power trigger signal is given to the control pole (so that the control-cathode PN junction is switched on), the device can be quickly excited to the on-state, and then it can be maintained in the on-state without continuing to maintain the trigger current. At this point, if the current drops below the maintenance current, the device can return to the blocked state. This characteristic enables the thyristor rectifier to achieve precise control of electrical power.

3. Application scenarios

5SGY3545L0017 thyristor active rectifier is widely used in power system, industrial control and motor drive fields. In the power system, it can be used for power regulation, voltage control and voltage regulation and DC power supply. In the field of industrial control, it can be used for motor speed regulation, electric heating equipment control and DC power supply.

The main parameters of 5SGY3545L0017 thyristor active rectifier include:

Rated current (IR) : The maximum steady state current that the thyristor can withstand.

Blocking voltage (VRRM) : The maximum reverse voltage the thyristor can withstand, that is, the maximum voltage it can withstand without conducting.

Conduction current (ITAV) : The average conduction current of thyristor in normal working condition.

On-voltage drop (Vt) : The average voltage drop of thyristor in the on-state, that is, the forward voltage.

Control Angle (α) : The control Angle is the phase difference between the trigger voltage of the thyristor and the AC voltage. By adjusting the control Angle, the on-time of thyristor can be controlled, so as to realize the rectifier function of the circuit.
