S3DHE3/57T is a single-phase unity power factor auxiliary thyristor rectifier that is widely used for industrial applications because of its compact size, high reliability and high power.
S3DHE3/57T is a thyristor rectifier working with high efficiency (up to 97%) and rapid current responsivity. Based on the requirement of auxiliary rectifying diodes, S3DHE3/57T is designed to reduce the size and improve the power, thereby increasing the output power. The rectifier consists of a main rectifying thyristor, an auxiliary rectifying diode and a control circuit connected to the main rectifying thyristor. The main thyristor controls the current and voltage, while the auxiliary diode provides additional current to improve the overall power efficiency. In addition, the rectifier is equipped with protective devices to prevent overcurrent, overload and short circuit condition.

S3DHE3/57T has a wide range of applications and can be used in various industries including automotive, household appliances, lighting, instrumentation, and energy production. For instance, in automotive industries, the rectifier is used to supply a steady and constant current for continuous operation of the car. Furthermore, in the household appliances, S3DHE3/57T rectifier provides the necessary current and voltage for the operation of devices like washing machine, lights, and ovens. In the lighting industry, the rectifier is used to control the power of the lamps by adjusting the current and voltage so as to provide suitable brightness intensity.

The working principle of S3DHE3/57T is that the conduction state between the anode and the cathode will be switched off after the anode voltage has decreased to a certain value and the control circuit is triggered. When the anode voltage increases to the same certain value, the state between the anode and the cathode will be switched on and the current flows through the rectifier to the output port. Thus, the current and voltage are regulated continuously by switching the conduction state of the anode and the cathode.

The efficiency of S3DHE3/57T rectifier is significantly improved by the use of additional auxiliary rectifying diode and hence allows for higher power output with smaller size and better control. In addition, the rectifier uses a unique design of insulation layer to improve the reliability and stability of the operation. All these features make S3DHE3/57T a desirable choice for applications requiring rapid current responsivity and energy efficiency.
