There is no difference. The terms "firing" and "triggering" both mean exactly the same.
As long as the voltages applied to both the anode and the gate have the correct values and polarities for a particular design of thyristor, "firing" or "triggering" will cause current to switch on between the thyristor's anode and cathode. The current will then continue to flow for as long as the correct source voltage polarity is maintained onto the anode.
Another opinion
If the input signal is given to a thyristor, it is said to be gated. Because of gating pulse the thyristor gets triggered ( cause & effect relationship). Once the thyristor is triggered the charged particles starts moving inside the different layers. A noise is created called "SHOT NOISE", due to the movement of charged particles. Heat energy is dissipated due to this movement of charged particles. Once the thyristor reaches this stage it is said to be fired. Hence, there is a minute difference between these three terms. But all these terms are being used interchangeably.

What is the thyristor firing circuit?
The thyristor is basically used a switch in an AC circuit to control the amount of power fed to the load. To turn on this switch an "electric" pulse should be applied to the Gate terminal of the Thyristor. A circuit which supplies the "electric" pulse is called the firing circuit.
What is the difference between an SCR and a TRIAC?
A thyristor is another name for an SCR, which stands for Silicon Controlled Rectifier.Thyristors or SCRs are bi-directional devices used to control the flow of AC current. Once triggered, the device remains "on" until the next wave of current crosses zero after the trigger is removed.For more information about thyristors or SCRs see the Related link shown below.
What is firing angle in thyristors?
A sinusoidal AC waveform is divided up into 360 degrees, with the positive half and the negative half of the waveform combined into a kind of circle. The firing angle simply refers to the point on the waveform, as measured in degrees (thus 'angle') which the thyristor is triggered into conduction. Answer2: Firing angle is the phase angle of the voltage at which the scr turns on. There are two ways of turning an scr on..one is by applying a gate current or by applying a voltage across the scr until it becomes greater than the breakover voltage.... Answer3: Thyristor need gate current and voltage to make it conduct. The firing angle is the sinusoidal increasing voltage. As it rises a voltage is reached with enough power to fire to trigger the gate. That voltage is the angle considering that a sinusoidal is 360 degrees per cycle.
What is the difference between uncontrolled and controlled rectifierWhich is advantageous and why?
Uncontrolled rectifiers, such as diode rectifiers, allow current to flow in one direction but do not control the output voltage or current, leading to less efficiency and limited applications. In contrast, controlled rectifiers, like thyristor-based systems, can regulate the output by adjusting the firing angle, allowing for better voltage and current control. Controlled rectifiers are generally more advantageous for applications requiring precise power management, such as in motor speed control and power supplies, due to their ability to optimize performance and efficiency.
What is ac chopper?
AC chopper is also called AC voltage controller. In AC voltage controller, we use 2 thyristors as switching element. In AC chopper we use MOSFET or IGBT as switching element with diodes in bridge rectifier for bidirectional flow of current. This use of mosfet switch has the following advantages over thyristor: * no separate firing circuit are needed for Mosfet ( it can be driven directly by interfacing it with MC) whereas firing circuits are needed for SCR. *when the line current drops to zero SCR turns off due to natural commutation( when it reaches 172 deg) ; mosfet- user control - we can turn on and off as per our requirement. * snubber circuit is needed for thyristor phase control method. By using mosfet in diode rectifier provides internal snubber

What is the relationship between the firing delay angle and the input power factor?
The firing delay angle is the point in the AC cycle at which a thyristor starts conducting. By adjusting this angle, the power factor of the system can be controlled as it affects the balance between real power and reactive power. A smaller firing delay angle can improve the power factor by reducing the phase difference between voltage and current.

How thyristor used in induction furnace?
Thyristor is used for Rectifiying and inverting the power supply in induction furnace. The parallel Resonance Coils (Current Control Furnaces) Control the Furance power up to 40% by controlling the firing angle of the rectifier inverter and remaining 60% controlled by inverter thyristor control. In rectifier they are varying the thyristor firing angle from 15 deg to 45 deg. (in sin wave)
What is the conduction angle for each thyristor in a single phase semi-converter for discontinuous conduction and extinction angle βπ?
In a single-phase semi-converter operating under discontinuous conduction, each thyristor conducts for a conduction angle of α to β, where α is the firing angle and β is the extinction angle. The conduction angle for each thyristor is therefore given by the formula ( \theta = \beta - \alpha ). Since the conduction is discontinuous, this angle is typically less than 180 degrees, resulting in each thyristor conducting for a part of the AC cycle, followed by a period where it is off. In general, the conduction angle can vary based on the firing angle and load conditions, but the key point is that it occurs only for the duration between firing and extinction.
