Inverter power supply and power supply system applying same

一种逆变电源及应用所述逆变电源的供电系统

Abstract

The utility model discloses an inverter power supply and a power supply system applying the same. The inverter power supply comprises a charger, an energy storage unit, a synchronous detection module, an inverter and a system controller, wherein the charger is connected with the energy storage unit to charge an energy storage power supply for energy storage; the synchronous detection module detects the frequency and the phase of a main power supply, generates a detection signal and outputs the detection signal to the system controller; and the system controller generates a pulse signal for driving connection and disconnection of a switching tube in the inverter according to the received detection signal, and outputs the pulse signal to the inverter to control the inverter to invert a direct-current power supply output by the energy storage unit into an alternating-current power supply which has the same frequency and phase as those of the main power supply for output. The inverter power supply solves the problem of low efficiency of the conventional online type uninterruptible power system (UPS), overcomes the defect that in the conventional backup type UPS, a fast switching condition is unavailable, meets a requirement on continuous power supply of a backward state load, and feasibly ensures the continuity of the work of a sensitive load.
本实用新型公开了一种逆变电源及应用所述逆变电源的供电系统,包括充电器、储能单元、同步检测模块、逆变器和系统控制器;所述充电器连接储能单元,为储能电源充电蓄能;所述同步检测模块检测主电源的频率和相位,生成检测信号输出至所述的系统控制器;所述系统控制器根据接收到的检测信号生成用于驱动逆变器中开关管通断的脉冲信号输出至所述的逆变器,进而控制逆变器将储能单元输出的直流电源逆变成与主电源同频率、同相位的交流电源输出。本实用新型的逆变电源不仅解决了传统在线式UPS效率低下的问题,而且克服了传统后备式UPS不具备快速切换条件的缺陷,满足了后级负载的连续供电要求,切实保证了敏感负载工作的连续性。
