Method for measuring electrical current levels in a power switching device |
摘要 |
A method for determining an electrical current value using at least two current sensing circuits. One current sensing circuit is provided if the current value is below a switching threshold. The other current sensing is provided if the current value is above a switching threshold. Both current sensing circuits having a processing means to process the current signal and a determining means to determine the value of the current signal.
