Abstract： |
A double tuned filter based on a controlled reactor is composed of capacitor C1, controlled reactor L1, capacitor C2, reactor L2, a double tuned filter and a controlled reactor control circuit, among which, the parallel branches of capacitor C1, controlled reactor L1, reactor Lo, capacitor C2 and rector L2 are orderly serial, the double tuned filter is parallel to the system side. This invention alters the output reacting value of the reactor by altering the DC control voltage of the controlled reactor, therefore, the filter parameter can be changed according to the variance of the system parameter to enable the filter to resonate continuously and keep a good filter result.variance of the system parameter to enable the filter to resonate continuously and keep a good filter result. |
