Abstract

The invention discloses a parallel inverter power supply system, which comprises a cabinet, wherein a DC input power distribution unit, an AC output power distribution unit, a static bypass switch module, a monitoring module and 1-20 inverter modules connected in parallel are arranged in the cabinet; input ends of the inverter modules are connected with the DC input power distribution unit; the inverter modules connected in parallel are connected with the input end of the static bypass switch module; an output end of the static bypass switch module is connected with a change-over switch; and DC voltage output by the DC input power distribution unit is transformed through the inverter modules connected in parallel to generate AC sine-wave voltage. Phase locking can be carried out on the parallel system and electric supply, so that the condition that AC output is uninterruptedly switched to a bypass under the condition of overload or failure of the inverter system is ensured, the capacity of the system can reach over 60KVA, resources can be efficiently utilized and an AC power supply with high stability and high purification degree can be provided.

Description

technical field [0001] The invention relates to a parallel inverter power supply system, which belongs to the technical field of inverter power supplies. Background technique [0002] The parallel inverter module adopts high-frequency power conversion technology design, small size, high power density, stable and reliable operation, and constitutes an inverter power system. It is suitable for all kinds of communication rooms with 48V and 24V basic power supply and needs to ensure uninterrupted AC power supply, and can also be widely used in solar and wind power generation and other fields. The system capacity of the existing inverter power supply is not high, and it cannot efficiently utilize resources and provide high-stability, high-purity AC power supply. Contents of the invention [0003] The object of the present invention is to provide a parallel inverter power supply system that can efficiently utilize resources and provide high stability and high degree of purifica...
