DEVICE FOR THE SELF-GENERATION OF AN OVER-VOLTAGE AND FOR THE SIMULTANEOUS CONTROL OF AN ACTUATOR HAVING ONE OR MORE INDUCTANCES, AND CONTROL METHOD THEREOF

摘要

The invention relates to a device for simultaneously increasing the voltage across the terminals of a load (20) and controlling the inductor (9a) of an actuator (9), without using any inductor other than that of the actuator. For this purpose, the inductor of the actuator is separated into two coil portions (24, 25) between which an intermediate terminal (26) is located. A power source (27) is connected to said intermediate terminal (26), preferably via a diode (28). The inductor of the actuator is located in an H bridge made up of four switching elements Q1, Q2, Q3, Q4 which are preferably transistors.
