Magnetic flux valves can be used in electromagnetic (EM) power converters to electronically control output signals of the EM power converters. An input signal is provided to an EM power converter that includes two or more core sections in which at least once core section includes a magnetic flux valve having an adjustable reluctance. The EM power converter has one or more primary windings and one or more secondary windings wound around one or more core sections. One or more control signals are provided to the one or more magnetic flux valves to control a reluctance or reluctances of the one or more magnetic flux valves, affecting magnetisms coupling between the primary and secondary windings. An output signal is generated, in which the output signal is a function of the input signal and the one or more control signals.
