• H03F 9/02 current-controlled, i.e. the load current flowing in both directions through a main coil
• H03F 9/04 voltage-controlled, i.e. the load current flowing in only one direction through a main coil, e.g. Logan circuits
• H03F 9/06 Control by voltage time integral, i.e. the load current flowing in only one direction through a main coil, whereby the main coil winding also can be used as a control winding, e.g. Ramey circuits
