Control circuit for predominantly inductive loads, in particular, electroinjectors
A control circuit (100) for supplying a load with current (Ii) having a high-amplitude portion with a rapid leading edge, and a lower-amplitude portion. The circuit is input-connected (102, 103) to a low-voltage supply source, and comprises a number of actuator circuits (106) parallel-connected betw...

| description | A control circuit (100) for supplying a load with current (Ii) having a high-amplitude portion with a rapid leading edge, and a lower-amplitude portion. The circuit is input-connected (102, 103) to a low-voltage supply source, and comprises a number of actuator circuits (106) parallel-connected between the input terminals (102, 103) and each including a capacitor (Ci) and a load (Li). Each actuator circuit (106) also comprises a first controlled switch (SWi) between the respective load (Li) and a reference line (105), for enabling energy supply and storage by the respective load. A second controlled switch (SWR) is provided between the capacitor line (112) and the load line (104), for rapidly discharging the capacitors into the load (Li) selected by the first switch (SWi) and recirculating the load current, or for charging the capacitors (Ci) with the recirculated load current. |
