Research On The Intellectualized High Performance
Sine Wave Inverter Power Supply
ABSTRACT : Along with the development of industry and science technology, request to the function of sine wave inverter is more and more high. As an equipment of DC to AC power conversion, sine inverter takes on the broad market in both industry and folk applications. The purpose of this system is realizing high performance, multifunction and intelligence. This system uses microcontroller 8051 and microcontroller W77E58 to control the inverter sub-system and the keyboard supervising sub-system separately. This system not only can be used as independent inverter power supply but can switch with power grid mutrally.
At the beginning, the basic topology and working theory of the inverting circuit is introduced. Following, the paper analyses and discusses the issues of hardware composing, parameter choice, controlling methods, and software implementing in the system. On the base, the Intellectualized High Performance Sine Wave Inverter is designed successfully.
