Abstract It consists of main and emergency power switching circuit, main loop magnetic combinated voltage-stablizing circuit, phase-sensitive-track voltage-stablizing circuit and switching accelerating circuit. The advantages are: quick switch speed between main and emergency power supplys, keeping vibration of 25Hz phase-sensitive-track circuit and making signal command system working safely and reliably without red light band flashing. By using magnetic combinated voltage-stablizing technology, it gats wider voltage-stablizing range, higher voltage-stablizing precision, small voltage waveform distortion and strong anti-interference ability etc.
