Abstract
A pulse current application device, including: a first switching element and an inductive load connected in series between a power supply and a reference potential; a plurality of first commutation circuits connected in parallel to the inductive load between the reference potential and a connection point of the first switching element and the inductive load, and each including a current application target and a second switching element connected in series; a second commutation circuit connected in parallel to the inductive load; a third switching element connected between the inductive load and the reference potential; and a regenerative diode connected between the power supply and a connection point of the inductive load and the third switching element, the regenerative diode being configured to return a current flowing therethrough back to the power supply while the third switching element is in a cut-off state.
