Q2. In an electronic power circuit, the rate of change of current (di /
dt) exceeds the limit specified in the semiconductor switch data
sheet.
Which of the following options can be considered as a scientific
solution to this problem? More than one option is possible.
1- Increasing the speed of turning on the key by increasing the
excitation current in the initial moments of the connected command.
2- Increasing the dimensions of the heatsink connected to the key.
3- Replace the switch with another switch that has the ability to
withstand voltage and current similar to the larger allowable di / dt
unit.
4- Using inductive sniper for the key.
5-Using series resistance with switch.
