Transistor chopper protection circuit |
摘要 |
A circuit for protecting the transistor of a high current transistor chopper from damage due to inductive energy stored in the chopper circuit when the transistor is biased nonconductive. The inductive energy charges a capacitor connected in parallel with the transistor, and a return circuit returns the energy stored in the capacitor to the source while the transistor is nonconductive and to the load when the transistor is subsequently biased conductive.
