This article mainly introduces the advantage of synchronous multi-phase DC/DC converter in decreasing ripple current and increasing efficiency and gives result of simulation and practice.

像这样低电压和大电流的电源主要存在两个问题：①由于输出电压极低，很难提高电源效率；②由于负载电阻极低，若采用传统方式

Adopting multiplexing technique and making use of communication line between CSC and CS to achieve simultaneous transmission of ISDN signal and electric power. According to the variation of circuit equivalent resistance to design detection circuit, which can judge that the line is short circuit or open circuit and the commercial power is working normally or failure. When the reserve power supply is working, the system judges its operation status by voltage and current detection circuit. Making use of the characteristic of the gas discharge tube to achieve suspension system detection of power line touching.
