Abstract

A method for controlling an actuator (L), particularly for an injector, in an internal combustion engine, the actuator (L) comprising an excitation circuit connected between a first pin (HS) and a second pin (LS), the method comprising the steps of:- applying a predetermined voltage (Vcc) across the excitation circuit, through a supply voltage source (2);acquiring signals representative of the actual voltage (VL) present across the excitation circuit of the actuator (L) and the actual current (IL) flowing into the circuit;- setting a current setpoint and a voltage setpoint based on said actual voltage (VL) and actual current (IL); andforcing the actual voltage (VL) to be equal to the voltage setpoint and the actual current (IL) to be equal to the current setpoint. The method is characterized in that it further comprises the steps of:- providing a control circuit arrangement for the actuator (L) having a first MOSFET (M1) connected between the supply voltage source (2) and the said first pin (HS) of the excitation cicuit, an inductance (6) connected between the first MOSFET (M1) and the said first pin (HS), a second MOSFET (M2) connected between the second pin (LS) of the excitation circuit and a voltage reference, a third MOSFET (M3) connected between the said second pin (LS) and the supply voltage source (2) and a fourth MOSFET (M4) connected between the said first pin (HS) and the second pin (LS);and forcing said actual voltage (VL) and actual current (IL) by controlling the switching of the four MOSFETs (M1-M4) according to at least one of a predetermined set of operating modes.
