Inductor designs and methods are provided. An inductor can include a first core and a second core. The first core can be larger than the second core and the second core can be seated within the inner diameter of the first core. A first and a second wire can be provided that each wrap around the first core and the second core. The first core can have less windings than the second core.

Inductor designs for reducing magnetic interference

Methods and apparatus for reducing Miller effect in SiC MOSFETs are provided. An example apparatus includes a plurality of SiC MOSFETs and a Miller current cancellation circuit configured to mitigate Miller current induced by switching transients associated with the plurality of SiC MOSFETS. The Miller current cancellation circuit includes a two-stage voltage sampling circuit configured to sample a drain to source voltage of a SiC MOSFET of the plurality of SiC MOSFETs, a voltage inverting circuit configured to invert the sampled drain to source voltage, and an injection capacitor configured to generate, by way of receiving the inverted sampled drain to source voltage as input, inverse Miller current to mitigate the Miller current within the plurality of SiC MOSFETS.
