conduction angle

The image of the conduction angle derives from amplifying a sinusoidal signal.

Thyristor conduction angle is the total angle through which the thyristor usually conducts power.

The thyristor conduction angle is considered to be the most direct method to analyse thyristor voltage controlled RL loads.

The conduction angle can be adjusted by changing drive level or temperature, and determines which part of the I/V curve is used and therefore the relative strengths of the different harmonically related outputs.

A "Class D" amplifier uses some form of pulse-width modulation to control the output devices; the conduction angle of each device is no longer related directly to the input signal but instead varies in pulse width.

Power amplifier circuits (output stages) are classified as A, B, AB and C for analog designs-and class D and E for switching designs based on the proportion of each input cycle (conduction angle), during which an amplifying device passes current.
