Abstract: The article introduces in detail the process of designing the hardware and software of the network inverter based on embedded system. This paper introduces the process of design in the following three parts: 1. The design and realization of the hardware of SVPWM inverter. IPM PM20CSJ060 is used to form chopping circuit of main circuit, ARM single chip computer LPC2292 is regarded as control center of the system control circuit. 2. The development of hardware of Ethernet interface. 3. The development of software of inverter. The development of the whole system software based on μC/OS-II is completed.
