Saturable inductor protection circuit for inductive load driver |
摘要 |
Methods and apparatus are disclosed for relieving stresses related to reverse recovery of free-wheeling diodes of power inverter circuits used to drive inductive loads by utilizing saturating inductors which are connected between switching transistors of the inverter circuit and the inductive load. Circuit elements are also connected to the switching devices of the inverter circuits for initially conducting free-wheeling current through an inductive load upon the turn-off of an inverter transistor.
