Abstract


Nowdays the requirement for reliability, capacity and performance of power supply system has become strictly,as the rapid development of technology. Inverter parallel technology is one of the hottest current power technology research point, use the parallel inverter technology, we can make large-capacity power supply and redundant power supply. The traditional inverter parallel control technology exists many insufficiencies. Since the CAN-bus has many advantage, such as the real-time, high reliability features, we can use it to control the individual parallel inverter. All the inverter is connected only by the can bus, totally realized the distribution management of the parallel inverter.The Single-phase inverter main circuit of this paper is the full-bridge inverter circuit. This paper Conducted a modeling analysis to the Single-phase inverter and also got the transfer function of the system. Since the output filter is very important to the parallel inverter, we design its capacitance and get the values of the inductance. The control of the inverter is Inner outer voltage loop current control,also had gave the output waveform of the inverter experimental.In the next chapter,had made a model composed by two single inverter parallel system, analyzed the circulation of the parallel system, and got the relationship between the output of voltage and frequency with active power and reactive power under different and the under different Connection resistances, gave the PQ droop control equations under different conditions based on this relationship. Also, we analyzed the two inverters and the load impedance connection between the difference of both flow.Then introduced the CAN bus used in power electronics, and gives the advantages of CAN hardware and software design and inverter output power calculate method. Use the imformation of active power and reactive power exchanged by CAN bus,this paper proposed a program based on the power droop control. Finally, this paper make two single inverter parallel system simulation and get the test waveforms. The results showed that both of the inverter current effect is nice, and this program is feasible.
