The embodiment of the invention provides a controllable reactor and a method for controlling the reactance value of the same, so as to solve a problem that the reactance value of a reactor cannot be changed more quickly in a very-low frequency communication scene. The controllable reactor comprises a controller and N controllable reactor modules in series connection. The controller is used for receiving a reactance value control command, determining the working state control signal of each controllable reactor module through using the reactance value in the reactance value control command andthe reactance value of each controllable reactor module when each controllable reactor module is in a working state, and outputting the determined working state control signals to the corresponding controllable reactor modules, wherein the reactance values of the controllable reactor modules are zero when the controllable reactor modules are in a non-working state. Each controllable reactor moduleis used for receiving and executing the corresponding working state control signal. Because the controller is employed for controlling the working states of the controllable reactor modules, not in amechanical control mode, the reactor can be controlled more quickly, and then the reactance parameters can be changed more quickly.
Description
technical field [0001] The present application relates to the field of communication technologies, and in particular to a controllable reactor and a method for controlling the reactance value of the controllable reactor. Background technique [0002] At present, the sending process of the very low frequency transmitter station is mainly to change the parameter size of the reactance element in the tuning matching circuit so that the transmitter outputs the maximum antenna current during carrier tuning and maintain this state. After the tuning is completed, select The exciter works, and then sends a report, wherein the antenna loop reaches resonance when the maximum antenna current is output when the carrier is tuned. [0003] Since the thyristor-controlled controllable reactance device and the magneto-controlled controllable reactance device are not suitable for very low frequency communication scenarios, the existing very low frequency transmitter antenna tuning feed circuit...
