Definitions
- a first circuit breaker can be, for example, a high-side switch, which connects the inductive load for magnetization with a first supply voltage, preferably a positive voltage.
- a second power switch can be, for example, a low-side switch, which connects the inductive load for magnetization with a second supply voltage, preferably with a ground voltage.
- the first power switch can be executed, for example, as a PMOS FET.
- the second power switch can be executed, for example, as an NMOS FET.
- FIG. 1 shows a schematic block diagram of a first exemplary embodiment of a current regulator for an inductive load in a vehicle according to the invention.
- Control with constant frequency and variable duty cycle as possible as a scheme in which the respective circuit breaker T1, T2 is turned on for a constant period of time and a turn-off of the power switch T1, T2 is varied, or in which the respective power switch T1, T2 is turned off for a constant period of time and a duty cycle of the power switch T1, T2 is varied.
- Free-running voltage represents, while in the off state, the first switch T F i locks in the freewheel and the freewheeling current flows completely through the clamp diode Z D.
- the current flows in the freewheel either through the first switch T F i or through the clamp diode Z D to the first supply voltage
- the diode D arranged in series with the source terminal S prevents a current flow via the resistors R GS and R G or the parasitic diode of the first switch T F i when the power switch T2 is turned on. If the amplitude of the drive signal GHS corresponds to the first supply voltage U B , the
