Abstract
A pulse current application circuit for applying a pulse current to a current application target. The pulse current application circuit includes a first switching element and an inductive load connected in series between a power supply and a reference potential, a second switching element connected in series with the current application target, the second switching element and the current application target being connected between the reference potential and a connection point of the first switching element and the inductive load, and a commutation circuit connected in parallel to the inductive load, the commutation circuit having a current flowing therethrough and having no current flowing therethrough respectively when the second switching element is in a cut-off state and a conductive state.
