PCT No. PCT/DE90/00157 Sec. 371 Date Sep. 9, 1991 Sec. 102(e) Date Sep. 9, 1991 PCT Filed Mar. 5, 1990 PCT Pub. No. WO90/10972 PCT Pub. Date Sep. 20, 1990.A switching regulator employing pulse width control or pulse frequency control of an actuator includes a current limiting device which receives a signal that is a function of current through the actuator and a signal that is a function of turn-on pulses for the actuator. The actuator is blocked by the current limiting device if the signal that is a function of the turn-on pulses for the actuator becomes smaller than the signal that is a function of the current through the actuator.
