TF(Fall Time) loss simulation
Download as PPTX, PDF0 likes35 views
This document describes a switching waveform circuit containing a BJT transistor, two diodes, and various resistors and inductors. The circuit parameters include time periods, voltages, and currents. Graphs show the voltage and current waveshapes over time as the BJT transistor switches on and off, with the power dissipated by the transistor varying according to the "tf" parameter value.
