The area under the curve of the gate characteristics of thyristor give...
As the gate characteristics is a plot of Ig vs Vg consisting of two curves one for the maximum values & other for the minimum the area between them gives the total average gate power dissipation. (A very important parameter in designing of the triggering circuits).

The area under the curve of the gate characteristics of thyristor give...
The gate characteristics of a thyristor represent the relationship between the gate current and the gate voltage required to trigger the thyristor into conduction. The gate characteristics curve is typically plotted with the gate current (IG) on the y-axis and the gate voltage (VG) on the x-axis.
To understand why the area under the curve of the gate characteristics represents the total average gate power dissipation, let's break it down into the following points:
1. Gate Power Dissipation:
Gate power dissipation (PG) is the power consumed by the gate circuit of the thyristor. It is given by the product of the gate voltage and the gate current: PG = VG * IG.
2. Average Gate Power Dissipation:
The average gate power dissipation is the average value of the gate power dissipation over one complete cycle of operation. It is calculated by integrating the instantaneous power dissipation over the cycle and dividing it by the cycle period.
3. Integrating the Gate Power Dissipation:
To find the total average gate power dissipation, we need to integrate the gate power dissipation over the gate characteristics curve. This can be done by calculating the area under the curve.
4. Integration of the Gate Power Dissipation:
The area under the curve represents the integral of the gate power dissipation with respect to time. Since power is the product of voltage and current, the integral of power with respect to time is the product of the integral of voltage with respect to time and the integral of current with respect to time.
5. Total Average Gate Power Dissipation:
By integrating the gate power dissipation over the gate characteristics curve, we are essentially calculating the total average gate power dissipation. This value represents the average power consumed by the gate circuit of the thyristor over one complete cycle of operation.
In conclusion, the area under the curve of the gate characteristics of a thyristor represents the total average gate power dissipation. This is because the power dissipation is the product of the gate voltage and the gate current, and integrating this power dissipation over the gate characteristics curve gives us the total average gate power dissipation.
