CPC H02M 1/32 (2013.01) [H02M 3/02 (2013.01); H02M 1/0009 (2021.05); H02M 1/0025 (2021.05)] | 9 Claims |
1. A current limiting circuit comprising:
a circuit configured to detect when an input or output current of a DC to DC converter exceeds or falls below a threshold; and
a controller configured to:
store a first value representative of a level of an output voltage of the DC to DC converter in response to the input or output current exceeding or falling below a first threshold;
store a second value representative of the level of the output voltage in response to the input or output current falling below a second threshold; and
modify a control signal based on the first and second values,
wherein the control signal is modified based on the first and second values so that the control signal brings the output voltage to an intermediate voltage level between the level of the output voltage represented by the first value and the level of the output voltage represented by the second value.
