When driving electromagnetic devices with square pulses there are a range of effects that can cause problems. Freewheel diode placed across an inductive load. Why Are My Igbts Continously Being Shorted Protecting Microcontroller From Inductive Loads Electrical How Do I Protect The Discrete Outputs On A Magelis Xbtgc2330 When an inductive load is de energized quickly the collapsing magnetic field opposes the sudden change and creates an electromagnetic force with the same polarity in order to. Diode protection for inductive loads . How do you protect against inductive kick back. If you want to use relays to drive inductive loads in a short experiment you can content yourself with a little over sizing of the relays and it will probably work quite well for some time. This type of circuit increases the release time more than the cr type. Since ind...
