Methods and apparatus for current sensing in mutually coupled inductors |
摘要 |
Methods and apparatus for current sensing in mutually coupled inductors according to various aspects of the present invention may operate in conjunction with a control system adapted to control current through the inductors and multiple current sensors connected to the control system. Each current sensor may comprise a series combination comprising a capacitor and a resistor. The series combination may be connected in parallel with one of the inductors, and may be adapted to generate branch inductor current signals according to a sensed current in the connected inductor. In addition, a coupling capacitor may be coupled between at least two of the current sensors to compensate a time constant of the current sensor for mutual coupling inductance between the inductors.
