Excerpt from Average Power Dissipated in a Diode Swept Along Its Reverse Characteristic It will be shown how a determination may be made of the average power dissipation in any device which has a characteristic that can be enclosed over regions of significant power dissipation by a right tri angle in the way drawn in Fig. L to enclose the curve R. The approach to the problem involves the calculation of the average power dissipated in a hypothetical device having a characteristic with an adjustable parameter. The calculation is used to develop an upper and lower bound on the value of the average power dissipated in a real device. When dealing with devices with thermal time constants that are large enough compared with the period of the power supply to make an average temperature meaningful a method is presente( which will make it possible for the characteristics of a group of similar devices to be examined under approximately the same heating conditions. This method consists of extending the swept characteristics to a calculable curve in the voltage-current plane which may be drawn on the cathode ray tube.
