Abstract: In order to solve the problem of 25 Hz phase detecting track circuit because of the ballast pollution, the paper presents a  adaptive voltage stabilizing circuit. It consist of rectifier filter circuit, intelligent voltage comparison circuit and executive circuit. The adaptive voltage stabilizing circuit can eliminate fault of red light strip, and get good result of shunting. The field test shows the effectives of the circuit.

Key words: 25?Hz , phase detecting track circuit, adaptive, voltage stabilizing circuit
