Abstract:

According to the special requirements of power supply for seismic station, a new single-phase emergency power supply control system is proposed in this paper. The principle and structure diagram of the system is illustrated. The control strategies of the system and hardware design of key circuits are discussed in detail. The emergency power supply control system adopts high-property C8051F310 single chip micro-computer. According to the monitoring value of input voltage, the system switches between charging and inverting. Main circuit of inverting uses single-phase full-bridge topology. To correct a power factor, charging system applies boost circuit to make input current follow to a given current reference. Experiments validate the feasibility of the proposed design.
