METHOD FOR CONTROLLING AT LEAST ONE INDUCTIVE CONSUMER BY MEANS OF A PULSE WIDTH MODULATED CONTROL SIGNAL |
摘要 |
<p>A method for driving at least one inductive load using pulse width modulated control signals, via a PWM control unit, the control pulses of the PWM control signals connecting the load to and disconnecting it from a d.c. supply voltage via a semiconductor output stage. To prevent the formation of an a.c. voltage occurring on the d.c. supply voltage in the case of pulse-wise loading of the same by the PWM control signal, the PWM control unit is assignable a supplementary device including a storage capacitor and/or storage inductor having a semiconductor switch, and the semiconductor switch is controllable by the PWM control unit switch on one charging current circuit powered by the d.c. supply voltage for the storage capacitor and/or the storage inductor.</p> |
