Three-phase voltage sensor with active crosstalk cancellation |
摘要 |
Active crosstalk cancellation in a multi-phase system is achieved using a capacitive voltage divider for each phase in the multi-phase system. A voltage measurement is obtained for the desired phase and each additional phase of the multi-phase system. A product is generated for each additional phase by multiplying each additional phase voltage measurement by a corresponding predetermined constant. The product for each additional phase is subtracted from the voltage measurement of the desired phase.
