In a circuit for protecting the transistor 18 of a high current transistor chopper from damage due to inductive energy stored in the chopper circuit when the transistor is biased non-conductive, the inductive energy charges a capacitor 34 connected in parallel with the transistor, and a return circuit 30 returns the energy stored in the capacitor to the source 16 while the transistor is non-conductive and to the load 10 when the transistor is subsequently biased conductive. |
