P1100EAL

Triggered thyristors, or TSS for short, have been around since the 1960s. They are used for the protection of electrical equipment from transient voltage surges. They can be used in a wide range of applications, from driver circuits to circuits for lighting and consumer electronics. In this article, we will explore the P1100EAL application field and its working principle.

The primary application for the P1100EAL triggered thyristor is to control the power switch and motor speed in high-power motor drives. It can also be used for pulse width modulation (PWM), to provide a controlled and uniform voltage to devices such as digital circuits. These types of thyristors are also used in induction cooking, as they are often used to control the switching speed of the induction coils.

The working principle behind the triggered thyristor is based on the process of current commutation, which is the process of switching electric current in the opposite direction. When the thyristor is connected to a power source, a small current will flow from the gate of the thyristor to the emitter, 2-3mA in the case of the P1100EAL. This current triggers the thyristor and the reverse voltage at the anode and the cathode causes a commutation event. This commutation event allows current to flow in the opposite direction, from the anode to the cathode, and by controlling the polarity of the voltage applied to the gate, current commutation can be controlled and the associated power switch can be operated. The P1100EAL thyristor will have a peak current rating of up to 1100A and is capable of operating at a frequency of up to 150kHz.

Triggered thyristors are used in a variety of applications, ranging from automotive applications to industrial machinery and appliances. Not only can thyristors be used to control the power switch in electric equipment, but they can also be used for pulse width modulation. By using pulse-width modulation, the thyristor can provide a uniform voltage output, as it is able to modulate the width of the pulses, allowing for better control.

TSSs are also used for snubber circuits, which are used to dampen the effects of electrical noise, as well as to protect electrical circuits from excessive voltage and current. The P1100EAL thyristor is also used for pulse-width modulation in induction cooking which allows for greater accuracy and control of the heating coils.

In conclusion, the P1100EAL Triggered Thyristor is a versatile device which is used in a variety of applications. It can be used for power switching, motor speed control, pulse width modulation, and snubber circuits. Its high peak current rating and capability to operate up to 150kHz make it suitable for use in modern motor drives and induction cooking.
