Design of switching power with N+1 hot standby

In this paper, a kind of power, the high frequency switching power system, is introduced. This power system overcomes the shortcoming of phase-controlled power, especially in its construction of modularization, design of N+1 hot standby. This system contains rectifier module and monitor module. The monitor module takes charge of controlling each rectifier module and communicating with the hoer monitor system. it can realize remote-detecting, remote-controlling, remote-adjustment. Monitor module takes on the management of the system. It sends out control command and acquires the operating situation of rectifier module. The system contains N+1 rectifier module, there is no main rectifier module, ad modules are in same authority, they output almost same power. if one module is invalidated the other will take charge of the burden of the invalidate one, so the reliability of the system is high than usual.
