Circuit arrangement for controlling switched-mode power supply, has control signal generating unit generating current limiting signal for causing limitation of load current on steady load current and for outputting frequency control signal |
摘要 |
<p>The arrangement (2) has a load measuring unit (21) for measuring a load measuring variable (SL) proportional to a load current flowing through a load to a secondary winding. A threshold value unit (22) is provided for checking/verifying whether the measured load variable exceeds a threshold value. A control signal generating unit (23) generates a current limiting signal for causing a limitation of the load current on a maximum steady load current and for outputting a frequency control signal and the limiting signal to a control unit, when the measured load variable exceeds the threshold value. An independent claim is also included for a method for controlling a switched-mode power supply/switched network.</p> |
